onsemi PMIC - Supervisors CAT1022WI-45-T3

The CAT1022WI-45-T3 is a supervisory circuit that integrates a 2k-bit CMOS EEPROM with a power supply voltage monitor and a watchdog timer. It operates within a voltage range of 2.7 V to 5.5 V and supports various systems including 5 V, 3.3 V, and 3 V configurations, with five selectable threshold voltage options. The device features a manual reset input and provides a reset output that is active low. The watchdog timer ensures system reliability by resetting the system if it becomes unresponsive. The EEPROM supports a 16-byte page write buffer and is designed for low power consumption, with a data retention capability of up to 100 years and 1,000,000 program/erase cycles. The CAT1022 is available in multiple package types, including an 8-pin SOIC, making it suitable for various applications in microcontroller-based systems.
