G690/G691
Microprocessor Reset IC
Features
General Description
ꢀPrecision Monitoring of +3V, +3.3V, and +5V
Power-Supply Voltages
The G690/G691 are microprocessor (µP) supervisory
circuits used to monitor the power supplies in µP and
digital systems. They provide excellent circuit reliability
and low cost by eliminating external components and
adjustments when used with +5V, +3.3V, +3.0V- pow-
ered circuits.
ꢀFully Specified Over Temperature
ꢀAvailable in Three Output Configurations
Push-Pull RESET Output (G690L)
Push-Pull RESET Output (G690H)
Open-Drain RESET Output (G691L)
ꢀ140ms min Power-On Reset Pulse Width
ꢀ10µA Supply Current
These circuits perform a single function: they assert a
reset signal whenever the VCC supply voltage declines
below a preset threshold, keeping it asserted for at
least 140ms after VCC has risen above the reset
threshold. Reset thresholds suitable for operation with
a variety of supply voltages are available.
ꢀGuaranteed Reset Valid to VCC = +1V
ꢀPower Supply Transient Immunity
ꢀNo External Components
ꢀ3-Pin SOT89, SOT23 and SC70 Packages
The G691L has an open-drain output stage, while the
G690 have push-pull outputs. The G691L’s open-drain
RESET output requires a pull-up resistor that can be
connected to a voltage higher than VCC. The G690L
have an active-low RESET output, while the G690H
has an active-high RESET output. The reset com-
parator is designed to ignore fast transients on VCC,
and the outputs are guaranteed to be in the correct
logic state for VCC down to 1V.
Applications
ꢀComputers
ꢀControllers
ꢀIntelligent Instruments
ꢀCritical µP and µC Power Monitoring
ꢀPortable / Battery-Powered Equipment
ꢀAutomotive
Low supply current makes the G690/G691 ideal for
use in portable equipment. The G690/G691 are avail-
able in 3-pin SOT89 or SOT23 or SC70 packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress rat-
ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of
the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
Applications Information
A microprocessor’s (µP’s) reset input starts the µP in a
known state. The G691L/G690L/G690H assert reset to
prevent code-execution errors during power-up,
power-down, or brownout conditions. They assert a
reset signal whenever the VCC supply voltage declines
below a preset threshold, keeping it asserted for at
least 140ms after VCC has risen above the reset
threshold. The G691L uses an open-drain output, and
the G690L/G690H have a push-pull output stage.
Negative-Going VCC Transients
In addition to issuing a reset to the µP during
power-up, power-down, and brownout conditions, the
G691L/G690H/G690L are relatively immune to short-
duration negative-going VCC transients (glitches).
Figure 1 shows typical transient duration vs. reset
comparator overdrive, for which the G691L/G690H/
G690L do not generate a reset pulse. The graph was
generated using a negative-going pulse applied to VCC,
starting 0.5V above the actual reset threshold and
ending below it by the magnitude indicated (reset
comparator overdrive). The graph indicates the maxi-
mum pulse width a negative-going VCC transient can
have without causing a reset pulse. As the magnitude
of the transient increases (goes farther below the reset
threshold), the maximum allowable pulse width de-
creases. Typically, for the G69_ _463 and G69_ _438,
a VCC transient that goes 100mV below the reset
threshold and lasts 7µs or less will not cause a reset
pulse. A 0.1µF bypass capacitor mounted as close as
possible to the VCC pin provides additional transient
immunity.
Connect a pull-up resistor on the G691L’s RESET out-
put to any supply between 0 and 5.5V.

Ensuring a Valid Reset Output Down to VCC = 0
100
When VCC falls below 1V, the G690 RESET output
no longer sinks current—it becomes an open circuit.
Therefore, high-impedance CMOS logic inputs con-
nected to RESET can drift to undetermined voltages.
This presents no problem in most applications since
most µP and other circuitry is inoperative with VCC
below 1V. However, in applications where RESET
must be valid down to 0V, adding a pull-down resistor
to RESET causes any stray leakage currents to flow

is not critical; 100kΩ is large enough not to load
RESET and small enough to pull RESET to ground.

A 100kΩ pull-up resistor to VCC is also recommended
for the G691L if RESET is required to remain valid
for VCC < 1V.

Interfacing to µPs with Bidirectional Reset Pins
VCC
Since the RESET output on the G691L is open drain,
this device interfaces easily with µPs that have bidi-
rectional reset pins, such as the Motorola 68HC11.

G691L Open-Drain RESET Output Allows Use with
Multiple Supplies
Generally, the pull-up connected to the G691L will
connect to the supply voltage that is being monitored
at the IC’s VCC pin. However, some systems may use
the open-drain output to level-shift from the monitored
supply to reset circuitry powered by some other supply
(Figure 4). Note that as the G691L’s VCC decreases
below 1V, so does the IC’s ability to sink current at

RESET . Also, with any pull-up, RESET will be pulled
high as VCC decays toward 0. The voltage where this
occurs depends on the pull-up resistor value and the
voltage to which it is connected.

Benefits of Highly Accurate Reset Threshold
Most µP supervisor ICs have reset threshold voltages
between 5% and 10% below the value of nominal
supply voltages. This ensures a reset will not occur
within 5% of the nominal supply, but will occur when
the supply is 10% below nominal.

Figure 4. G691L Open-Drain RESET Output Allows
Use with Multiple Supplies
When using ICs rated at only the nominal supply ±5%,
this leaves a zone of uncertainty where the supply is
between 5% and 10% low, and where the reset may or
may not be asserted.
The G69_ _463/G69_ _308 use highly accurate circuitry
to ensure that reset is asserted close to the 5% limit,
and long before the supply has declined to 10% below
nominal.
