The CAT1027WI-28-GT3 from On Semiconductor is a dual voltage supervisory circuit integrated with a 2k-bit serial EEPROM. It is designed for microcontroller-based systems, providing power supply monitoring and brown-out protection. The device features a precision VCC sense circuit with multiple threshold voltage options, including an adjustable input down to 1.25V, supporting various system voltages like 5V, 3.3V, and 3V.
The supervisor circuit ensures system integrity during power up/down and brownout conditions by activating reset signals when power supply voltages fall out of tolerance. The CAT1027WI-28-GT3 includes an active low reset output with a minimum timeout of 130ms. It also offers an auxiliary voltage sensor input for monitoring a second system supply.
This supervisor is available in an 8-SOIC surface mount package, making it suitable for space-constrained applications. It operates within an industrial temperature range of -40°C to 85°C (TA). The integrated 2k-bit EEPROM memory supports 400 kHz I2C bus communication and features a 16-byte page write buffer with built-in inadvertent write protection.
