Smart Power Switch
FEATURES
DESCRIPTION
• 300mA Continuous Output Current
The UC37131, UC37132 and UC37133 are a family of smart power
switches which can drive resistive or inductive loads from the high side or
low side.
• Low Side or High Side Switch
Configuration
The UC37132 is available in 14 pin (DIP), 16 pin (SOIC), or 20 pin (CLCC)
packages and can accommodate both low side (load to VCC) or high side
(load to GND) configurations. The UC37131 and UC37133 are exclusively
for a low side or a high side configuration respectively and both are avail-
able in an 8 pin package. Both high side and low side configurations provide
high current switching with low saturation voltages which can drive resistive
or inductive loads.
• 8V to 65V Operation
• Overload and Short Circuit Protection
• Power Interruption Protection
• +6V Regulated Voltage
• 2mA Quiescent Current
The input to the switch is driven by a low voltage signal, typically 5V. Addi-
tionally, UC37132 features adjustable hysteresis. The output of the device
can switch a load between 8V and 65V. Output current capability is 300mA
continuous or 700mA peak.
• Programmable Overcurrent and
Power Interruption Protection
• 1% to 30% Programmable Input
Comparator Hysteresis (on UC37132)
The device also has inherent smart features that allow for programmable
turn-on delay in enabling the output following startup. The same capacitor
that specifies the turn-on delay is also used to program a VCC power inter-
ruption time. If VCC drops below a threshold for a time specified by this ca-
pacitor, the output is turned off and a new turn-on delay will be re-triggered.
Similarly, if high current persists longer than the response delay, the output
driver will operate in a very low duty cycle mode to protect the IC.

The UC37131/2/3 family of devices features a 6V
bandgap reference that is used to bias on-chip logic. Al-
though the 6V reference is not trimmed, this bandgap ref-
erence provides less than 200ppm/°C. It is also used to
generate the on-chip 3V input comparator threshold and
is needed for the programmable hysteresis. The on-chip
reference has 8mA maximum current sourcing capacity
that is designed to power up external circuitry.

will turn back on. If the overcurrent fault is still present,
the chip will operate in a very low duty cycle (approxi-
mately 0.7%) based on the discharge (driver on) and
charge time (driver off) of the CDEL capacitor. This
overcurrent timing makes the chip act "smart" by allowing
very high currents needed to drive large capacitive loads
without setting off an overcurrent fault.
Input Comparator
The input comparator is a high gain comparator with hys-
teresis that fully switches with either a small signal
(30mV, minimum for 1% hysteresis) or a logic signal (0 to
6V max). Only a 5mV overdrive of the 3V threshold is
needed to switch the driver.
The overcurrent and current limit thresholds are pro-
grammed with the resistor R

Once the turn-on signal is gated through from the input
comparator, the output transistor is turned on. The output
drive transistor is a composite PNP, NPN structure. This
is a specially designed structure that keeps all the drive
current needed for the load to be sourced through the LS
pin. This keeps the overall power dissipation to less than
4mA independent of the load.

output a logic 0 to the NAND gate and turn off the output
driver. If the fault goes away prior to CDEL being dis-
charged to 1.3V, the chip will resume normal operation
without going through a turn-on delay.
The power interrupt normal operation consists of the chip
turning the driver immediately back on if the interrupt
goes away prior to CDEL reaching its lower threshold as
described above. The CDEL capacitor is chosen based
upon the maximum power interrupt time (t ) allowed
without the output experiencing a turn-on delay. This in-
The output driver also has a 72V zener diode wired be-
tween its base and collector. This allows the output to
swing and clamp to 72V above ground when discharging
an inductive load in a low side application. The inductive
zener clamp can discharge the 250mA to 400mA full
load current. This consequently allows the LS pin to
safely swing above VCC. Similarly, the 72V zener diode
will allow the HS pin to safely swing and clamp 72V be-
low LS/VCC when discharging an inductive load in a high
side application. This 72V zener diode simplifies the user
application by eliminating the need for external clamp di-
odes.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
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) Only one of markings shown within the brackets will appear on the physical device.

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.
