AMIS-70020 Datasheet (AMI SEMICONDUCTOR) - Power Failure Elapsed Time Counter

AMIS-70020, Power Failure Elapsed Time Counter

The AMIS-70020 is a timer IC that measures the duration of power failures of up to five hours.

The AMIS-70020 starts and stops counting automatically as it is triggered by the voltage of the input signal VCC.

When VCC gets lower than the reference signal VDD - VTH, a power cut-off is flagged and the
