General Description

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 AMIS-70020 starts counting.
