Note 1: 100% production tested at T
A
= +25°C. Overtemperature limits guaranteed by design.
Note 2: Condition at V
CC
= 1V is guaranteed only from T
A
= 0°C to +70°C.
Note 3: Monitored voltage 5V/3.3V is also the device supply. In the typical condition, supply current splits as follows: 25µA for the
resistor-divider, and the rest for other circuitry.
