... Provide memory write protection through internal chip-enable gating during supply or processor faults. 4) Include one of the following options: a manual reset input (MAX6365), a watchdog timer function (MAX6366), a battery-on output (MAX6367 auxiliary user-adjustable reset input (MAX6368). The MAX6365–MAX6368 operate from V ages as low as 1.2V. The factory preset reset threshold voltages range from 2 ...
