Product Summary
The MAX6747KA46+T is a low-power microprocessor (μP) supervisory circuit, which monitors single/dual system supply voltages from 1.575V to 5V and provides maximum adjustability for reset and watchdog functions. The MAX6747KA46+T device asserts a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or when manual reset is pulled low. The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold. The reset function features immunity to power-supply transients.
