nanoPower Supervisor and Watchdog Timer
General Description
Benefits and Features
The MAX16152/MAX16153/MAX16154/MAX16155 ultralow-current supervisory circuits monitor a single system
supply voltage and the integrity of code execution by a
microprocessor or microcontroller. These supervisors assert the reset output whenever the VCC supply voltage is
greater than the minimum operating voltage, but less than
the reset threshold. After the supply voltage rises above
the reset threshold, the reset output remains asserted for
the reset timeout period, and then deasserts. Reset voltage thresholds are available from 1.50V to 5.0V in approximately 100mV increments.

A watchdog timer circuit monitors microprocessor or microcontroller activity. During normal operation, the microprocessor or microcontroller should repeatedly toggle the
watchdog input (WDI) before the supervisor’s watchdog
timeout period elapses to confirm that the system is executing code properly. If the microprocessor or microcontroller does not provide a valid watchdog input transition
before the timeout period expires, the supervisor asserts
a watchdog (WDO) output to signal that the system is not
executing code as expected. The watchdog output pulse
can be used to reset the microprocessor or microcontroller, or it may be used to interrupt the system to warn of
execution errors. The MAX16152 and MAX16153 feature
a manual reset input (MR) to allow an external pushbutton
or logic signal to initiate a reset pulse. The MAX16154 and
MAX16155 feature a logic input (WD_EN) that allows the
system to enable and disable the watchdog function.
The MAX16152 and MAX16154 are offered in a 0.86mm
x 1.27mm 6-bump WLP, while the MAX16153 and
MAX16155 are offered in 6-pin SOT23 package. All devices operate over the -40ºC to +125ºC temperature
range.

MAX16154/MAX16155
nanoPower Supervisor and Watchdog Timer
Detailed Description
The MAX16152/MAX16153/MAX16154/MAX16155 are ultra-low-current supervisory circuits that monitor a single system
supply voltage and assert an active-low reset signal when the supply voltage drops below the factory-trimmed reset
threshold. After the supply voltage rises above the threshold voltage, the reset output remains asserted during the
reset timeout period, and finally asserts after the timeout period ends. In addition, a watchdog timer circuit monitors
microprocessor or microcontroller activity. During normal operation, the microprocessor or microcontroller toggles the
WDI input periodically with a valid logic transition (low to high or high to low). If the WDI input is toggled within the
watchdog timeout period (tWD), the internal timer is cleared and restarted, and the WDO output remains high. If the input
is not strobed before the timeout period expires, the watchdog output is asserted low for a period equal to the watchdog
output pulse width (tWDO).
Input Threshold
The MAX16152/MAX16153/MAX16154/MAX16155 monitor VCC with ±2.5% accuracy across the full temperature and
supply voltage ranges. The input threshold is programmable from 1.5V to 5V in approximately 100mV increments.
Contact Maxim for thresholds not listed in the Selector Guide.
Watchdog
The MAX16152/MAX16153/MAX16154/MAX16155 offer flexible watchdog circuits for monitoring microprocessor or
microcontroller activity. During normal operation, the internal timer is cleared and restarted each time the WDI input
undergoes a valid logic transition (high-to-low) within the selected timeout period (tWD). The WDO remains high as long
as the WDI input is strobed within the selected timeout period. If the WDI input is not strobed before the timeout period
expires, the watchdog output is asserted low for the watchdog output pulse width (tWDO). The MAX16154 and MAX16155
feature a logic input to enable/disable the watchdog timer during normal operation while the MAX16152 and MAX16153
does not. The watchdog timer for the MAX16152 and MAX16153 can be disabled by leaving the WDI floating.
Watchdog Startup Delay
All devices feature a factory-set startup delay. The startup delay provides an initial delay for the watchdog timer circuit
to power up and initialize before assuming responsibility for normal watchdog input monitoring. For the MAX16152 and
MAX16153, monitoring of the WDI input begins after the startup time is complete. For the MAX16154 and MAX16155,
monitoring of the WDI input begins after the startup delay if WD_EN is pulled high. To ensure that the system generates
no undesired watchdog outputs, the routine watchdog input transitions should begin before the minimum startup delay
period has expired. The startup delay is activated after the reset output is deasserted. See the Selector Guide for
available watchdog startup delay options.
Watchdog Timeout Period
An open-drain, active-low watchdog output (WDO) asserts if a valid watchdog input transition is not received before the
timeout period elapses. See the Selector Guide for available watchdog timeout period options.
Watchdog Enable Input (WD_EN)
The MAX16154 and MAX16155 feature an active-high logic input (WD_EN) to enable or disable the watchdog function.
Applying a logic-low to WD_EN disables the watchdog function, causing the MAX16154 and MAX16155 to ignore any
signals applied to WDI. Applying a logic-high to WD_EN enables the watchdog function after 300μs (max) of setup time
tSETUP. See Figure 1, Figure 2, and Figure 3 for more details.

Watchdog Input Signal
Watchdog timing is measured from the last WDI falling edge associated with a pulse of at least 1µs (min) in width.
WDI transitions are ignored when WDO and/or RST are asserted, and during the startup delay period. Watchdog input
transitions are also ignored for a setup period (tSETUP) of up to 300μs after WD_EN is asserted.
Reset Timeout Period
The MAX16152/MAX16153/MAX16154/MAX16155 feature an active-low open-drain reset output (RST) that asserts low
when VCC drops below the factory-set threshold voltage, VTH. The reset output remains asserted as long as VCC
remains below the threshold voltage. When VCC rises above the threshold voltage plus the required hysteresis, the reset
output remains asserted during the reset timeout period, and then deasserts. See Figure 4 for more details. See the
Selector Guide for available reset timeout period options.

output after 250ns (typ) delay period (tMRD). The reset output remains asserted as long as MR is held low. The reset
output deasserts after the reset timeout period when MR is released. See Figure 5 below for MR timing characteristics.

Applications Information
Power Supply Bypassing
The MAX16152/MAX16153/MAX16154/MAX16155 operate from a 1.2V to 5.5V supply. Bypass VCC to ground with a
0.1μF capacitor as close to the device as possible to improve transient immunity. For fast-rising VCC transients, additional
capacitance may be required. VCC rise time >50µs ensures proper operation.
Watchdog Software Considerations
To help the watchdog timer monitor software execution more closely, set and reset the watchdog input at different points
in the program, rather than pulsing the watchdog input high-low-high or low-high-low. This technique avoids a stuck loop,
in which the watchdog timer would continue to be reset inside the loop, keeping the watchdog from timing out. Figure 6
shows an example of a flow diagram where the I/O driving the watchdog input is set high at the beginning of the program,
set low at the end of every subroutine or loop, then set high again when the program returns to the beginning. If the
program should hang in any subroutine, the problem would be quickly corrected, since the I/O is continually set low and
the watchdog timer is allowed to time out, causing WDO to pulse.

Negative-Going VCC Transients Protection
The MAX16152/MAX16153/MAX16154/MAX16155 are relatively immune to short-duration negative-going VCC
transients (glitches). It is usually undesirable to reset the system when VCC experiences only small glitches. The Typical
Operating Characteristics show Maximum Transient Duration vs. Reset Threshold Overdrive, for which reset pulses are
not generated. The graph was produced using negative-going VCC pulses, starting above VTH and ending below the
reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse width that
a negative-going VCC transient may typically have without causing a reset pulse to be issued. As the amplitude of the
transient increases (i.e., goes farther below the reset threshold), the maximum allowable pulse width decreases. A 0.1µF
