Power Dissipation
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance
characteristics may degrade when the device is not operated under the listed conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The Human Body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200pF
capacitor discharged directly into each pin.
(4) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal
resistance, θJ-A, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperture is calculated
using:
Where the value of θJ-A for the VSSOP-10 package is 195°C/W in a typical PC board mounting and the DSBGA package is 220°C/W.

CIRCUIT INFORMATION
RESET OUTPUT
The Reset input of a µP initializes the device into a known state. The LM3710/LM3711 microprocessor
supervisory circuits assert a forced reset output to prevent code execution errors during power-up, power-down,
and brownout conditions.
RESET is ensured valid for VCC > 1V. Once VCC exceeds the reset threshold, an internal timer maintains the
output for the reset timeout period. After this interval, reset goes high. The LM3710 offers an active-low RESET;
The LM3711 offers an active-high RESET.
Any time VCC drops below the reset threshold (such as during a brownout), the reset activates. When VCC again
rises above the reset threshold, the internal timer starts. Reset holds until VCC exceeds the reset threshold for
longer than the reset timeout period. After this time, reset releases.
The Manual Reset input (MR) will initiate a forced reset also. See the MANUAL RESET INPUT (MR) section.
RESET THRESHOLD
The LM3710/LM3711 family is available with a reset voltage of 3.08V. Other reset thresholds in the 2.20V to
5.0V range, in steps of 10 mV, are available; contact Texas Instruments for details.
MANUAL RESET INPUT (MR)
Many µP-based products require a manual reset capability, allowing the operator to initiate a reset. The MR input
is fully debounced and provides an internal 56 kΩ pull-up. When the MR input is pulled below VMRT (1.225V) for
more than 25 µs, reset is asserted after a typical delay of 12 µs. Reset remains active as long as MR is held low,
and releases after the reset timeout period expires after MR rises above VMRT. Use MR with digital logic to assert
or to daisy chain supervisory circuits. It may be used as another low-line comparator by adding a buffer.
POWER-FAIL COMPARATOR (PFI/PFO)
The PFI is compared to a 1.225V internal reference, VPFT. If PFI is less than VPFT, the Power Fail Output PFO
drops low. The power-fail comparator signals a falling power supply, and is driven typically by an external voltage
divider that senses either the unregulated supply or another system supply voltage. The voltage divider generally
is chosen so the voltage at PFI drops below VPFT several milliseconds before the main supply voltage drops
below the reset threshold, providing advanced warning of a brownout.
The voltage threshold is set by R1 and R2 and is calculated as follows:
(1)
Note this comparator is completely separate from the rest of the circuitry, and may be employed for other
functions as needed.
LOW-LINE OUTPUT (LLO)
The low-line output comparator is typically used to provide a non-maskable interrupt to a µP when VCC begins
falling. LLO monitors VCC and goes low when VCC falls below VLLOT (typically 1.02 • VRST) with hysteresis of
0.0032 • VRST
.
WATCHDOG TIMER INPUT (WDI)
The watchdog timer input monitors one of the microprocessor's output lines for activity. Each time a transition
occurs on this monitored line, the watchdog counter is reset. However, if no transition occurs and the timeout
period is reached, the LM3710/LM3711 assumes that the microprocessor has locked up and the reset output is
activated.
WDI is a high impedance input.

SNVS150E –NOVEMBER 2000–REVISED MARCH 2013
SPECIAL PRECAUTIONS FOR THE DSBGA PACKAGE
As with most integrated circuits, the LM3710 and LM3711 are sensitive to exposure from visible and infrared (IR)
light radiation. Unlike a plastic encapsulated IC, the DSBGA package has very limited shielding from light, and
some sensitivity to light reflected from the surface of the PC board or long wavelength IR entering the die from
the side may be experienced. This light could have an unpredictable affect on the electrical performance of the
IC. Care should be taken to shield the device from direct exposure to bright visible or IR light during operation.
DSBGA MOUNTING
The DSBGA package requires specific mounting techniques which are detailed in TI Application Note AN-1112
(SNVA009). Referring to the section Surface Mount Assembly Considerations, it should be noted that the pad
style which must be used with the 9-pin package is the NSMD (non-solder mask defined) type.
For best results during assembly, alignment ordinals on the PC board may be used to facilitate placement of the
DSBGA device.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
