[Use] Dual voltage monitoring chip with watchdog 4K EEPROM

[performance parameters]

Available in SOIC-14 and TSSOP-14 packages. Working voltage is 2.7V-5.5V,

characteristic:

1. Dual voltage monitoring - three standard reset thresholds 4.6V / 2.9V 4.6V / 2.6V 2.9V / 1.6V - VTIRP2 can be programmed to 0.9V - adjustable reset threshold voltage with special programming timing - reset effective to VCC=1V, monitor two voltages or detect power failure.
2, backup power switching function
3, VOUT Vcc supply current 5mA ~ 50mA VBAT supply current 250A.
4. Failure detection register.
5. Optional power-on reset output time is 0.05S 0.2S 0.4S 0.8S.
