ISL88001, ISL88002, ISL88003 Pin Descriptions PIN ISL88001 ISL88002 ISL88003 PIN NAME PIN FUNCTION 1 1 GND Ground IC reference. 2 RST The RST pin is an active-low reset output that is pulled to GND (LOW) when reset is asserted. The ISL88001 is push-pull while the ISL88002 is open drain. 2 RST The RST pin is a push-pull active-high reset output that is pulled to VDD (HIGH) when reset is asserted. 3 3 VDD Supply Voltage and Monitored Input. The VDD pin is the IC power supply terminal and also the monitored input.

Principles of Operation The ISL88001, ISL88002, ISL88003 devices provide a low power, high accuracy solution for those voltage monitoring applications needing supply voltage supervision with power reset control. By integrating these features into small 3 Ld SC- 70 and 3 Ld SOT-23 packages and consuming as little as 160nA of supply current, these devices can lower system cost and reduce board space requirements.
