ASM802L
Overview
- 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-supply supervisors. Short-circuit and thermal protection have also been added. The ASM690A / ASM802L / ASM805L generate a reset pulse when the supply voltage drops below 4.65 V and the ASM692A / ASM802M generate a reset below 4.40 V. The ASM802L / ASM802M have power-fail accuracy to ±2%. The ASM805L is the same as the ASM690A except that RESET is provided instead of RESET.
