Typical Operating Characteristics (continued)
(VCC = full range, TA = +25°C, unless otherwise noted.)
Pin Description
Active-Low. Reset is asserted when VCC drops below VTH and remains asserted until VCC rises above VTH
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 VCC reset monitor. For noisy systems, bypass VCC with a 500pF
(min) capacitor.
VCC
4
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).

2
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 VCC if unused.
