ADM709RARZ General Description

The ADM709 contains a power supply monitor which generates a system reset during power-up, power-down and brownout conditions. When V_CC falls below the reset threshold, RESET goes low and holds the µP in reset. On power-up the RESET output is held low for 140 ms after V_CC rises above the threshold. The RESET output remains operational with V_CC as low as 1 V.
