CAT1163LI-30-G

Supervisors Overview

The CAT1163LI-30-G is a supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates an I2C serial CMOS EEPROM with 16K capacity and a precision reset controller featuring a watchdog timer. The device operates within a supply voltage range of up to 6 V, with a threshold voltage of 3 V and an overvoltage threshold of 3.15 V. It provides active high, active low, and open drain outputs, along with manual reset capability. The reset delay time is specified at 270 ms, and the component functions within a temperature range of -40°C to +85°C.
