Dual/Triple-Voltage
µP Supervisory Circuits
General Description
Features
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.
♦ Precision Monitoring of Multiple +1.8V, +2.5V,
+3.0V, +3.3V, and +5V Power-Supply Voltages
♦ Precision Factory-Set Power-Supply
Reset Thresholds
♦ 20µA Supply Current
♦ 100ms min Power-On Reset Pulse Width
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.

♦ Power-Supply Transient Immunity
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.

*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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

Reset Outputs
The MAX6351 provides two active-low, push-pull reset
outputs, one corresponding to each of its two moni-
tored voltages. The MAX6353/MAX6356/MAX6359 have
an active-low, push-pull reset output that is referenced
Detailed Description
Supply Voltages
The MAX6351–MAX6360 microprocessor (µP) superviso-
ry circuits maintain system integrity by alerting the µP to
fault conditions. These ICs monitor multiple-supply sys-
tems. The output reset state is guaranteed to remain
to V 1. The MAX6354/MAX6357/MAX6360 have an
CC
active-low, push-pull reset output that is referenced to
viable while either V 1 or V 2 is above +1V.
CC
CC
V
2. The MAX6352/MAX6355/MAX6358 provide an
CC
active-low open-drain reset. The reset outputs are
maintained as long as at least one of the supplies is
above +1V.
Threshold Levels
All the possible input voltage threshold level combina-
tions are indicated by a two-letter code in the Voltage
Threshold Levels table.
Negative-Going V

The MAX6351–MAX6360 are designed to ignore short

The MAX6355/MAX6356/MAX6357 provide an addition-

at RSTIN is typically 1.22V. To monitor a voltage higher

Watchdog Input
(MAX6358/MAX6359/MAX6360)
The MAX6358/MAX6359/MAX6360 include a dual-
mode watchdog timer to monitor µP activity. The flexi-
ble timeout architecture provides a startup mode,
allowing complicated systems to complete lengthy
boots, and a normal mode, allowing the supervisor to
provide quick alerts when processor activity fails.

µP Supervisory Circuits
During the normal operating mode, the supervisor will
issue a reset pulse for the reset timeout period (140ms
min) if the µP does not update the WDI with a valid tran-
sition (HIGH to LOW or LOW to HIGH) within the stan-
dard timeout period (1.6s min).

After each reset event (V

100kΩ
watchdog reset), there is an initial watchdog startup
timeout period of 25.6s. The startup mode provides an
extended period for the system to power up and fully
initialize all µP and system components before assum-
ing responsibility for routine watchdog updates. The
normal watchdog timeout period (1.6s min) begins at
the conclusion of the startup timeout period or after the
first transition on WDI before the conclusion of the start-
up period (Figure 3).
