The ON Semiconductor CAT1023WI-42-GT3 is a supervisory circuit integrated with a 2k-bit I2C EEPROM memory. It provides a system power supervisor with brown-out protection, operating in low-power CMOS technology. The memory interface utilizes a 400 kHz I2C bus.
This device features a precision VCC sense circuit and open-drain outputs for reset signals. It includes a 1.6-second watchdog timer to reset the system if it halts or hangs. The power supply monitor and reset circuit protect memory and system controllers during power up/down and brownout conditions. It supports 3V, 3.3V, and 5V systems with five reset threshold voltage options.
The CAT1023WI-42-GT3 is available in an 8-pin SOIC package, suitable for surface mounting. It operates within an industrial temperature range of -40°C to 85°C. The device includes a manual reset input and built-in inadvertent write protection for the EEPROM memory.
