Description
The HA16117F Series of ICs make a micro-processor (MPU) system fail-safe by monitoring its power supply to detect voltage drops, and monitoring a P-RUN (program running) pulse to detect system crashes.
Features
- Low power consumption : Operating (ACC pin low) = 0.5 mW (Typ) : Standby (ACC pin high) = 0.2 mW (Typ).
- Watchdog timer on/off control by ACC input signal.
- Independent auto-reset high and low times (tRH and tRL).
- Watchdog monitoring by frequency filtering (independent of duty cycle).
- High-precision low voltage detection (±2%).
- Space- and weight-saving 8-pin SOP package
