CAT1641YI-30-GT3

Supervisors Overview

The CAT1641YI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, housed in an 8-pin TSSOP package. It integrates a 64K CMOS EEPROM with I2C serial interface capabilities for data storage alongside power management functions. The device monitors a single input and features an open collector/drain output type with manual reset functionality. It operates without a watchdog timer or battery backup switch. Key electrical parameters include a maximum supply voltage of 5.5 V, a minimum operating voltage of 3 V, and an undervoltage threshold range of 4.25 V to 4.5 V. The reset delay time is specified at 5 microseconds. The component supports an operating temperature range from -40°C to +85°C and has a power dissipation rating of 1 W.
