MAX6361PUT23+ [Analog Devices]

The MAX6361–MAX6364 are low-power supervisory circuits with battery backup for microprocessor systems. They provide µP reset, backup battery switchover, and power failure warning. Operating from supply voltages as low as +1.2V, they offer factory-preset reset threshold voltages from 2.32V to 4.63V. Features include manual reset input (MAX6361), watchdog timer (MAX6362), battery-on output (MAX6363), and auxiliary adjustable reset input (MAX6364). They are available in three reset output structures: push-pull RESET, open-drain RESET, and open-drain RESET. The devices guarantee RESET/RESET valid down to 1.2V, have power-supply transient immunity, a 150ms minimum reset timeout period, and come in a small 6-pin SOT23 package.
