PST620
Overview
- Low current consumption
- Capacitors (super capacitor, large capacity chemical capacitor) are used for back-up power supply, lowering system cost
- Stable 1-chip microcomputer crystal oscillator rise time maintained with the built-in pulse shaver.
- In addition to power outage detection for main power supply (+5V), there are built-in pins to detect AC power supply and +5V power supply primary side
- Reset signal output by back-up power supply (super capacitor, large capacity chemical capacitor) detection Package
