DATASHEET
ISL88705, ISL88706, ISL88707, ISL88708, ISL88716,
ISL88813
Designed with high reset threshold accuracy and low power
consumption, the ISL88705, ISL88706, ISL88707,
ISL88708, ISL88716 and ISL88813 devices are
microprocessor supervisors that are designed to monitor
power-supply and battery functions in microprocessor
systems. They can help to lower system cost, reduce board
space requirements and increase the reliability of systems.
These devices provide essential functions such as supply
voltage supervision by asserting a reset output during
power-up and power-down as well as during brownout
conditions. An auxiliary voltage monitor is provided for
detecting power failures warning the system of low battery
conditions or presence detection. In addition, an
independent watchdog timer helps to monitor
microprocessor activity every 1.6s (typical). An active-low
manual reset is offered and reset signals remain asserted
until V
DD
returns to proper operating levels.
Users can increase the nominal 200ms power-on reset
time-out delay by adding an external capacitor to the C
POR
pin on the ISL88707 and ISL88708.
