OVERVIEW

The S24023 is a power supervisory device with 2,048 bits of serial E2PROM. It is fabricated using SUMMIT's advanced CMOS E2PROM technology and is suitable for both 3 and 5 Volt systems.

The memory is internally organized as 256 x 8. It features the I2C serial interface and software protocol allowing operation on a simple two-wire bus.

The S24023 provides a precision VCC sense circuit and an active low open-drain RESET output that drives low whenever VCC falls below VTRIP
