CAT1320YI-45-GT3

Supervisors Overview

The CAT1320YI-45-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It features an integrated 32K EEPROM and operates within a supply voltage range of 3 V to 5.5 V. The device monitors a single input with a threshold voltage of 4.5 V and provides an open collector/drain output type. It includes manual reset functionality but lacks a watchdog timer or battery backup switch. The reset delay time is specified at 5 us. Operating temperatures range from -40 C to +85 C, and it is housed in a TSSOP-8 package.

Supervisors Feature Summary

• Integrates 32K EEPROM for data storage alongside voltage supervision
• Provides manual reset capability for system control
• Features fast reset delay time of 5 us

Supervisors Applications

• CPU supervision systems
• Voltage monitoring in embedded devices
• Data retention applications requiring non-volatile memory
