ADM709MARZ-REEL

Processor Supervisor 4.4V 3V/3.3V/5V 8Pin SOIC N T/R

Product Details

The ADM709 contains a power supply monitor which generates a system reset during power-up, power-down and brownout 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 threshold. The RESET output remains operational with VCC as low as 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 found in the data sheet.

The ADM709 is available in 8-pin DIP and SOIC packages.
