GENERAL DESCRIPTION
The ADM8323/ADM8324 are supervisory circuits that monitor
power supply voltage levels and code execution integrity in
microprocessor-based systems. An on-chip watchdog timer
checks for activity within a preset timeout window. A reset
signal can also be asserted by an external push-button switch
through a manual reset input. The
RESET
output is either push-
pull (ADM8323) or open-drain (ADM8324).
A watchdog failure results in a low output on the
RESET
pin.
A failure can be triggered either by a fast watchdog error
(watchdog pulses too close together) or by a slow watchdog
error (no watchdog pulse within the timeout period). This
effectively gives a window in which to observe the watchdog
pulse. The watchdog timeout is measured from the last falling
edge of the watchdog input (WDI). There are eight different
watchdog windows available, as shown in Table 5.
Each device is available in a choice of 26 reset threshold options
from 2.5 V to 5 V in 100 mV increments. There are also four
reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms
(minimum).
The ADM8323/ADM8324 are available in a 5-lead SOT-23
package and typically consume only 10 μA, making them
suitable for use in low power portable applications.
