ALTERNATE WATCHDOG INPUT DRIVE CIRCUITS
The watchdog feature can be enabled and disabled under
program control by driving WDI with a three-state buffer (see
Figure 28). When three-stated, the WDI input floats, thereby
disabling the watchdog timer.
WATCHDOG
STROBE
Data Sheet
For the ADM8691 / ADM8695 , the watchdog period can be
extended under program control using the circuit shown in
low and the watchdog timeout is set by the external capacitor.
A 0.01 μF capacitor sets a watchdog timeout delay of 100 sec.
When the control input is low, the OSC SEL pin is driven high,
selecting the internal oscillator. The 100 ms or the 1.6 sec

period is chosen, depending on which diode is used, as shown
in Figure 29. With D1 inserted, the internal timeout is set to

100 ms; with D2 inserted, the timeout is set to 1.6 sec.
This circuit is not entirely foolproof, and it is possible for a
software fault to erroneously three-state the buffer, preventing
the ADM8690 / ADM8691 / ADM8695 from detecting that the

microprocessor is no longer operating correctly. In most cases,
a better method is to extend the watchdog period rather than
disable the watchdog.
