General Description
Benefits and Features
The MAX16152/MAX16153/MAX16154/MAX16155 ultra-
low-current supervisory circuits monitor a single system
supply voltage and the integrity of code execution by a
microprocessor or microcontroller. These supervisors as-

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 de-asserts. Reset volt-
age thresholds are available from 1.50V to 5.0V in approx-
imately 100mV increments.
● 6-Pin SOT23 Package
● -40°C to +125°C Operating Temperature Range
A watchdog timer circuit monitors microprocessor or mi-
crocontroller activity. During normal operation, the micro-
processor or microcontroller should repeatedly toggle the
watchdog input (WDI) before the supervisor’s watchdog
timeout period elapses to confirm that the system is exe-
cuting code properly. If the microprocessor or microcon-
troller 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 micro-
controller, 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.
Ordering Information appears at end of data sheet.
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 de-
vices operate over the -40ºC to +125ºC temperature
range.

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 (t
), the internal timer is cleared and restarted, and the WDO output remains high. If the
WD
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 (t
).
WDO
Input Threshold
The MAX16152/MAX16153/MAX16154/MAX16155 monitor V
with ±2.5% accuracy across the full temperature and
CC
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 Ordering Information table.
Watchdog
The MAX16152/MAX16153/MAX16154/MX16155 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 (t ). The WDO remains high as long
WD
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 (t
). The MAX16154 and MAX16155
WDO
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 start-up time is complete. For the MAX16154 and MAX16155,
monitoring of the WDI input begins after the start-up 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 de-asserted. 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 set up time
t
. See Figure 1, Figure 2, and Figure 3 for more details.

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 (t

Applications Information
Power Supply Bypassing
The MAX16152/MAX16153/MAX16154/MAX16155 operate from a 1.20V to 5.5V supply. Bypass V
to ground with a
CC
0.1μF capacitor as close to the device as possible to improve transient immunity. For fast-rising V
transients, additional
CC
capacitance may be required. V
rise time >50µs ensures proper operation.
CC
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.

width that a negative-going V transient may typically have without causing a reset pulse to be issued. As the amplitude
CC
of the transient increases (i.e., goes farther below the reset threshold), the maximum allowable pulse width decreases. A
0.1µF bypass capacitor mounted close to the V
pin provides additional transient immunity.
