ASM690A/692A, ASM802L/802M, ASM805L mP Power Supply Supervisor with Battery Backup Switch Description The ASM690A / ASM692A / ASM802L / ASM802M / ASM805L offers complete single chip solutions for power supply monitoring and control battery functions in microprocessor systems. Each device implements four functions: Reset control, watchdog monitoring, battery−backup switching and power failure monitoring. In addition to microprocessor reset under power−up and power−down conditions, these devices provide battery−backup switching to maintain control in power loss and brown−out situations. Additional monitoring capabilities can provide an early warning of unregulated power supply loss before the voltage regulator drops out. The important features of these four functions are: • 1.
