onsemi Integrated Circuits (ICs) - PMIC - Supervisors CAT1025LI25

The CAT1025LI25 from Quarktwin Technology Ltd. is a supervisory circuit that integrates a 2k-bit CMOS EEPROM with a power supply voltage monitor. It operates within a voltage range of 2.7V to 5.5V and features a 400kHz I¬=C bus interface. The device supports five threshold voltage options suitable for 5V, 3.3V, and 3V systems, ensuring reliable operation during power fluctuations. This product includes both active high and low reset outputs, with valid reset guaranteed at a supply voltage as low as 1V. It also features a manual reset input and a write protect pin, which disables write operations when activated. The CAT1025LI25 is designed for low power consumption and offers a robust data retention capability of up to 100 years, along with a high endurance of 1,000,000 program/erase cycles. The device is available in multiple package types, including an 8-pin DIP and various surface mount options, making it versatile for different applications. It operates over industrial and extended temperature ranges from -40¬?C to 125¬?C, making it suitable for a wide range of environments.
