MAXIM INTEGRATED / ANALOG DEVICES MAX807NCWET Supervisory Circuit
The MAX807 is a microprocessor supervisory circuit designed for power supply monitoring, backup-battery switchover, and watchdog functions in systems. It features high reset-threshold accuracy suitable for battery-powered applications, with reset outputs that ensure proper system startup and shutdown. The device provides two-stage power-fail warnings, manual reset control, and a watchdog timer to prevent system hangs. Its low supply current, high output current capability, and compatibility with SuperCaps make it ideal for portable, high-performance, and critical embedded systems requiring reliable power management.
