The MAX6365 MAX6368 MAX6367 MAX6366 Supervisory Circuits simplify power-supply monitoring, battery-backup control functions, and memory write protection in Microprocessor (P) systems. The circuits significantly improve the size, accuracy, and reliability of modern systems with an ultra-small integrated solution.
These devices perform four basic system functions:
Provide a P reset output during VCC supply power-up, power-down, and brownout conditions. Internally control VCC to backup-battery switching to maintain data or low-power operation for CMOS RAM, CMOS Ps, Real-Time Clocks and other digital Logic when the main supply fails.
Provide memory write protection through internal chip-enable gating during supply or processor faults.
Include one of the following options: a manual reset input MAX6365 , a watchdog Timer function MAX6366 , a battery-on output MAX6367 , or an auxiliary user-adjustable reset input MAX6368 . The MAX6365 MAX6368 MAX6367 MAX6366 operate from VCC supply voltages as low as 1.2V. The factory preset reset threshold voltages range from 2.32V to 4.63V (see Ordering Information). In addition, each part is offered in three reset output versions: push-pull active low, open-drain active low, or open-drain active high (see Selector Guide). The MAX6365 MAX6368 are available in miniature 8-pin SOT23 packages.
