■GENERAL DESCRIPTION:
The ADM709 contains a power supply monitor which generates a system reset during power-up, power-down and brown out conditions. When VCC 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 VCC rises above the thresh-old. The RESET output remains operational with VCC as lowas 1 V.
Three supply-voltage threshold levels are available suitable for+5 V, +3.3 V and for +3 V supply monitoring. The actual reset voltage threshold is given below.
The ADM709 is available in 8-pin DIP and SOIC packages.
