ASM690A Datasheet - ON Semiconductor

ASM690A uP Power Supply Supervisor

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.

ASM690A Features

* of these four functions are:

* 1.6 second watchdog timer to keep microprocessor responsive

* 4.40 V or 4.65 V VCC threshold for microprocessor reset at power

* up and power

* down

* SPDT (Single

* pole, Double

* throw) PMOS switch connects backup power
