Pin Descriptions
RST
The RST output is an open drain output, which is asserted
low whenever:
MR
The MR input is an active low debounced input to which a
user can connect a push-button to add manual reset
capability or use a signal to pull low. MR has an internal
pull-up resistor.
V
The V
this pin is compared against an internal factory-programmed
voltage trip point, V
device is initially powered and V
time thereafter when V
designed with hysteresis to help prevent chattering due to
noise and is immune to brief power-supply transients.

V2MON
The V2MON input is the second preset monitored voltage
that causes the RST output to go low when the voltage on
V2MON falls below V
V3MON, V4MON, and V5MON
The VxMON inputs provide monitoring and UV compliance
of three additional voltages through resistor dividers. A reset
is issued on the ISL88031 if the voltage on any VxMON falls
below the internal V
Principles of Operation
The ISL88031 device provides those functions needed for
monitoring critical voltages, such as power-supply and battery
functions in microprocessor systems. It provides such features
as Power-On Reset control, Supply Voltage Supervision, and
Manual Reset Assertion. The integration of all these features
along with competitive reset threshold accuracy and low power
consumption, makes the ISL88031 device suitable for a wide
