onsemi Supervisors CAT1024WI-25-GT3

The CAT1024WI-25-GT3 is a supervisory circuit designed for microcontroller-based systems, integrating a 2k-bit EEPROM memory with a power supervisor featuring brown-out protection. It operates on a 400 kHz I2C bus and supports supply voltages from 2.7 V to 5.5 V. The device includes a precision VCC sense circuit that activates reset signals when the supply voltage falls below specified thresholds, ensuring system stability during power fluctuations. The CAT1024 variant provides a single active low reset output, while the CAT1025 variant offers both active high and low outputs along with a write protect feature. The product includes a watchdog timer that resets the system in case of software or hardware failures. It is available in multiple package types, including SOIC, TSSOP, MSOP, and TDFN, with the TDFN package being particularly compact at 3 mm x 3 mm and 0.8 mm in height. The device is suitable for industrial applications, with an operating temperature range of -40¬8C to 85¬8C, and is compliant with RoHS standards.
