Note:
*1: 100% production tested at T_A = +25ºC. Over temperature limits are guaranteed by design.
*2: Conditions at V_CC = 1V is guaranteed only from T_A = 0ºC to +70ºC.
*3: Monitored voltage 5V/3.3V is also the device supply. In the typical condition, supply current splits as follows:25A for the
resistor-divider, and the rest is for other circuitry.
