MAX6351–MAX6360
General Description
The MAX6351–MAX6360 microprocessor (µP) supervisors with multiple reset voltages significantly improve system 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 startup 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 VCC1 and the other is referenced to VCC2. The MAX6353/MAX6356/MAX6359 offer
an active-low, push-pull reset output referenced to VCC1.
The MAX6354/MAX6357/MAX6360 offer an active-low,
push-pull reset output referenced to VCC2.
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.

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
absolute maximum rating conditions for extended periods may affect device reliability.

µP Supervisory Circuits
Supply Voltages
The MAX6351–MAX6360 microprocessor (µP) supervisory circuits maintain system integrity by alerting the µP to
fault conditions. These ICs monitor multiple-supply systems. The output reset state is guaranteed to remain
viable while either VCC1 or VCC2 is above +1V.

All the possible input voltage threshold level combinations are indicated by a two-letter code in the Voltage
Threshold Levels table.

Reset Outputs
The MAX6351 provides two active-low, push-pull reset
outputs, one corresponding to each of its two monitored voltages. The MAX6353/MAX6356/MAX6359 have
an active-low, push-pull reset output that is referenced
to VCC1. The MAX6354/MAX6357/MAX6360 have an
active-low, push-pull reset output that is referenced to
VCC2. The MAX6352/MAX6355/MAX6358 provide an
active-low open-drain reset. The reset outputs are
maintained as long as at least one of the supplies is
above +1V.
Negative-Going VCC Transients
The MAX6351–MAX6360 are designed to ignore short
negative-going V CC 1 and V CC 2 transients. See the
Maximum VCC Transient Duration vs. Reset Threshold

The MAX6355/MAX6356/MAX6357 provide an additional input to monitor a third voltage. The threshold voltage
at RSTIN is typically 1.22V. To monitor a voltage higher
than 1.22V, connect a resistive divider to the circuit as
shown in Figure 2. The threshold at VEXT is:

RST1 (1)
Note that RSTIN is powered by VCC1, and its voltage
must therefore remain lower than or equal to VCC1.
Watchdog Input
(MAX6358/MAX6359/MAX6360)
The MAX6358/MAX6359/MAX6360 include a dualmode watchdog timer to monitor µP activity. The flexible 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.

Detailed Description
MAX6351–MAX6360
Dual/Triple-Voltage
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 transition (HIGH to LOW or LOW to HIGH) within the standard timeout period (1.6s min).
After each reset event (VCC power-up, manual reset, or
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 assuming 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 startup period (Figure 3).

Figure 4. Ensuring a Valid Reset Low to VCC1 and VCC2 = 0
Ensuring a Valid RESET Output
Down to VCC = 0
In some systems, it is necessary to ensure a valid reset
even if VCC falls to 0. In these applications, use the circuit shown in Figure 4. Note that this configuration does
not work for the open-drain outputs of the MAX6352/
MAX6355/MAX6358.
Interfacing to µPs with
Bidirectional Reset Pins
Microprocessors with bidirectional reset pins will contend with the push-pull outputs of these devices. To
prevent this, connect a 4.7kΩ resistor between RESET
and the µP’s reset I/O port, as shown in Figure 5. Buffer
RESET as shown in the figure if this reset is used by
other components in the system.
