the capacitor may be replaced. Refer to the respective device data sheet to determine the capacitor value for
required timing.
5.9 CWD
A capacitor between the CWD pin and GND sets the watchdog timeout period t
WD
for TPS35-Q1 and
TPS3435-Q1 devices or the watchdog close window period t
WC
for TPS36-Q1 and TPS3436-Q1 devices. The
TPS36Q1EVM offers two pre-installed options: 0.01µF and 1µ. These capacitors correspond to 49.5ms and
4.95s t
WD
time delays for the TPS35-Q1 and TPS3435-Q1 devices, respectively. The t
WD
values are determined
by the SET0 and SET1 pins; please refer to
for a list of the values and the data sheet for the t
WD
calculation. Refer to
and
for suggested jumper settings. If other timing option is needed,
the capacitor can be replaced. Refer to the respective device data sheet to determine the capacitor value for
required timing.
