GENERAL DESCRIPTION

The ADM6326/ADM6328/ADM6346/ADM6348 devices provide

low cost solutions for protecting sensitive circuitry, such as micro-

processor and telecommunications circuitry.

microprocessor in a reset state until conditions have stabilized.

The reset output remains operational with V_CCas low as 1 V.

The ADM6326 and ADM6346 have an active low push-pull reset

output. The ADM6328 and ADM6348 have an active low open-

drain reset output, which requires an external pull-up resistor.

The ADM6326 and ADM6328 offer a choice of ten reset thresholds

in increments between 2.2 V and 3.08 V, whereas the ADM6346

and ADM6348 offer a choice of 14 reset thresholds between 3.3 V

and 4.63 V.

With built-in glitch immunity, ultralow supply currents, and

24 reset threshold voltage options, the ADM6326/ADM6328/

ADM6346/ADM6348 not only ensure that systems are immune

to fast transients on V_CC, but also that the devices are suitable

for monitoring a variety of supply voltages in low power,

portable equipment.

These devices provide a reset output during power-up, power-

down, and brownout conditions. On power-up, an internal
