CAT1162WI-28-T3

Supervisors Overview

The CAT1162WI-28-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 2.8 V with an overvoltage threshold of 3 V. The device provides a reset delay time of 270 ms and draws a working supply current of 3 mA. It supports manual reset functionality and offers active high, active low, or open drain output types. Packaged in an SOIC-8 surface-mount format, it functions without a watchdog timer or battery backup switch.
