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  
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-

Reset Comparator Overdrive, VTH- VCC (mV)  
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  
VCC  
to ground, holding RESET low (Figure 2). R1’s value  
is not critical; 100kΩ is large enough not to load  
RESET and small enough to pull RESET to ground.

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