GENERAL DESCRIPTION
The ADM6384 is a supervisory circuit that monitors power supply
voltage levels in microprocessor-based systems. A power-on reset
signal is generated when the supply voltage rises to a preset
threshold level. The debounced manual reset input of the
ADM6384 can be used to initiate a reset by means of an external
push button or logic signal.
The device is available in a choice of 31 reset threshold options,
from 1.58 V to 5.0 V. The minimum reset timeout periods are
1 ms, 20 ms, 140 ms, and 1120 ms.
The ADM6384 is available in a 4-lead SC70 package and typi-
cally consumes only 7 μA, making it suitable for use in low
power, portable applications.
