General Description
The MAX6323/MAX6324 microprocessor (P) supervi-
sory circuits monitor power supplies and P activity in
digital systems. A watchdog timer looks for activity out-
side an expected window of operation. Six laser-
trimmed reset thresholds are available with ±2.5%
accuracy from +2.32V to +4.63V. Valid RESET output is
guaranteed down to VCC = +1.2V.
The RESET output is either push-pull (MAX6323) or
open-drain (MAX6324). RESET is asserted low when
VCC falls below the reset threshold, or when the manual
reset input (MR) is asserted low. RESET remains assert-
ed for at least 100ms after VCC rises above the reset
threshold and MR is deasserted.
The watchdog pulse output (WDPO) utilizes an open-
drain configuration. It can be triggered either by a fast
timeout fault (watchdog input pulses are too close to
each other) or a slow timeout fault (no watchdog input
pulse is observed within the timeout period). The
watchdog timeout is measured from the last falling
edge of watchdog input (WDI) with a minimum pulse
width of 300ns. WDPO is asserted for 1ms when a fault
is observed. Eight laser-trimmed timeout periods are
available.
The MAX6323/MAX6324 are offered in a 6-pin SOT23
package and operate over the extended temperature
range (-40°C to +125°C).

*These devices are factory trimmed to one of eight watchdog-
timeout windows and one of six reset voltage thresholds. Insert
the letter corresponding to the desired watchdog-timeout window
(A, B, C, D, E, F, G, or H) into the blank following the number
6323 or 6324 (see Watchdog Timeout table). Insert the two-digit
code (46, 44, 31, 29, 26, or 23) after the letters UT for the desired
nominal reset threshold (see Reset Threshold Range table at end
of data sheet).
/V denotes an automotive qualified part.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
Note: There are eight standard versions of each device available
(see Standard Versions table). Sample stock is generally held on
standard versions only. Standard versions have an order incre-
ment requirement of 2500 pieces. Nonstandard versions have an
order increment requirement of 10,000 pieces. Contact factory for
availability of nonstandard versions.
