Dual/Triple-Voltage
μP Supervisory Circuits
General Description
The MAX6351–MAX6360 microprocessor (μP) supervi-
sors with multiple reset voltages significantly improve sys-
tem reliability and accuracy compared to separate ICs or
discrete components. If any input supply voltage drops
below its associated preset threshold, all reset outputs
are asserted. In addition, the outputs are valid as long as
either input supply voltage remains greater than +1.0V.
All devices in this series have an active-low debounced
manual reset input. In addition, the MAX6358/MAX6359/
MAX6360 offer a watchdog-timer input with a 46.4s start-
up timeout period and a 2.9s timeout period. The
MAX6355/MAX6356/MAX6357 offer an additional voltage
monitor input to monitor a third voltage.
The MAX6351 features two active-low, push-pull reset
outputs, one is referenced to V CC 1 and the other is refer-
enced to V CC 2. The MAX6353/MAX6356/MAX6359 offer
an active-low, push-pull reset output referenced to V CC 1.
The MAX6354/MAX6357/MAX6360 offer an active-low,
push-pull reset output referenced to V CC 2.
All these devices are offered with a wide variety of voltage
threshold levels, as shown in the Voltage Threshold
Levels table. They are available in 5- and 6-pin SOT23
packages and operate over the extended (-40°C to
+85°C) temperature range.

Note: Standard versions are shown in bold. Sample stock is gen-
erally held on the standard versions only. Contact factory for avail-
ability.
* The _ _ are placeholders for the threshold voltage levels of the
devices. Substitute the part number suffix in the Voltage Thres-
hold Levels table for the desired voltage level. All devices are
available in tape-and-reel only. There is a 2500 piece minimum
order increment for the SOT package.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
