X40021
Overview
- Dual voltage detection and reset assertion -Three standard reset threshold settings (4.6V/2.9V, 4.6V/2.6V, 2.9V/1.6V) -VTRIP2 programmable down to 0.9V -Adjust low voltage reset threshold voltages using special programming sequence -Reset signal valid to VCC = 1V -Monitor two voltages or detect power fail
- Battery switch backup
- VOUT: 5mA to 50mA from VCC; 250µA from VBATT
- Fault detection register
- Selectable power-on reset timeout (0.05s, 0.2s, 0.4s, 0.8s)
- Selectable watchdog timer interval (25ms, 200ms, 1.4s, off)
- Debounced manual reset input
- Low power CMOS -25µA typical standby current, watchdog on -6µA typical standby current, watchdog off -1µA battery current in backup mode
- 400kHz 2-wire interface
- 2.7V to 5.5V power supply operation
