ASM690A Overview
The ASM690A / ASM692A / ASM802L / ASM802M / ASM805L offers plete 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.
ASM690A Key Features
- 1.6 second watchdog timer to keep microprocessor responsive
- 4.40 V or 4.65 V VCC threshold for microprocessor reset at
- SPDT (Single-pole, Double-throw) PMOS switch connects backup
- 1.25 V threshold detector for power loss or general purpose voltage
