Typical Operating Characteristics (continued)
(V
CC
= full range, T
A
= +25°C, unless otherwise noted.)
Pin Description
Active-Low. Reset is asserted when V
CC
drops below V
TH
and remains asserted until V
CC
rises above V
TH
for the duration of the reset timeout period. The MAX6323 has a push-pull output and the MAX6324 has an
open-drain output. Connect a pullup resistor from
RESET
to any supply voltage up to +6V.
Watchdog Pulse Output. The open-drain
WDPO
output is pulsed low for 1ms (typ) upon detection of a fast
or slow watchdog fault.
WDPO
is only active when
RESET
is high.

Supply Voltage for the Device. Input for V

CC
with a 500pF
(min) capacitor.

Watchdog Input. The internal watchdog timer clears to zero on the falling edge of WDI or when
RESET
goes
high. If WDI sees another falling edge within the factory-trimmed watchdog window,
WDPO
will remain
unasserted. Transitions outside this window, either faster or slower, will cause
WDPO
to pulse low for 1ms
(typ).

Active-Low, Manual Reset Input. When
MR
is asserted low,
RESET
is asserted low, the internal watchdog
timer is reset to zero, and
WDPO
is reset to high impedance (open drain). After the rising edge of
MR
,
RESET
is asserted for at least 100ms. Leave
MR
unconnected or connect to V
CC
if unused.
