Watchdog Timer
The watchdog timer operates together with or indepen-
dently of the MAX16065/MAX16066. When operating in
dependent mode, the watchdog is not activated until the
sequencing is complete and RESET is deasserted. When
operating in independent mode, the watchdog timer is
independent of the sequencing operation and activates
immediately after V CC exceeds the UVLO threshold and
the boot phase is complete. Set r73h[4] to ‘0’ to config-
ure the watchdog in dependent mode. Set r73h[4] to ‘1’
to configure the watchdog in independent mode. See
Table 24 for more information on configuring the watch-
dog timer in dependent or independent mode.

Push-Pull Active-High Configuration
Dependent Watchdog Timer Operation
Use the watchdog timer to monitor F P activity in two
modes. Flexible timeout architecture provides an adjust-
able watchdog startup delay of up to 300s, allowing com-
plicated systems to complete lengthy boot-up routines.
An adjustable watchdog timeout allows the supervisor to
provide quick alerts when processor activity fails. After
each reset event (V CC drops below UVLO then returns
above UVLO, software reboot, manual reset ( MR ), EN
input going low then high, or watchdog reset) and once
sequencing is complete, the watchdog startup delay
provides an extended time for the system to power up
and fully initialize all F P and system components before
assuming responsibility for routine watchdog updates.
Set r76h[6:4] to a value other than ‘000’ to enable the
watchdog startup delay. Set r76h[6:4] to ‘000’ to disable
the watchdog startup delay.
