GENERAL DESCRIPTION
The ADM6326/ADM6328/ADM6346/ADM6348 devices provide
low cost solutions for protecting sensitive circuitry, such as micro-
processor and telecommunications circuitry.
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
timer holds RESET asserted for at least 100 ms. This holds the

microprocessor in a reset state until conditions have stabilized.
The reset output remains operational with V CC as 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.
These devices are available in a 3-lead SOT-23 package and
operate over the extended temperature range of ?40°C to +85°C.
