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.
up and power
down conditions, these devices provide battery
backup switching to maintain control in power loss and
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 to RAM if VCC fails.
- 1.25 V threshold detector for power loss or general purpose voltage
monitoring These features are pin.
- compatible with the industry standard power.
