MAX6365-68 Microprocessor Supervisory Circuits

Analog Devices MAX6365-MAX6368 Microprocessor Supervisory Circuits feature battery backup and chip-enable gating. These devices simplify power-supply monitoring, battery-backup control functions, and memory write protection in microprocessor (µP) systems. The circuits significantly improve the size, accuracy, and reliability of modern systems with an ultra-small integrated solution. These devices provide a microprocessor reset output during V_CC supply power-up, power-down, and brownout conditions. These devices internally control V_CC to backup-battery switching to maintain data or low-power operation for CMOS RAM, CMOS microprocessors, real-time clocks, and other digital logic when the main supply fails.
