Overview

AMIS-70020 Power Failure Elapsed Time Counter 1.
0 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.
During the counting phase the AMIS-70020 is powered by an external capacitor or by a primary battery and consequently operates independently of an external power supply.
Due to the low power design of the AMIS-70020, the device can count the full scale autonomously using the energy stored in a 10mF c...
