CAT1023YI-25-GT3

Supervisors Overview

The CAT1023YI-25-GT3 is a supervisory circuit manufactured by onsemi, designed for CPU supply monitoring. It integrates a 2-kbit serial EEPROM with the voltage supervisor in an 8-pin TSSOP package. The device monitors a single input with threshold voltages ranging from 2.55 V to 2.7 V and supports manual reset functionality. It includes a watchdog timer and offers active high, active low, or open drain output types. The reset delay time is specified at 200 ms, with a maximum power supply voltage of 5.5 V. Operating current is 10 uA, and it functions within a temperature range of -40°C to +85°C.
