Hi Steve,

The TPS38-Q1 device does not have a watchdog. Could you please inform the device in question here? Do you mean TPS36-Q1 if so yes the pinout option A can disable the watchdog by connecting the CWD pin to ground.

Thanks,
Joshua

Hi Steve,

For TPS35-Q1 same as the TPS36-Q1 the watchdog can be disabled with pinout option A by connecting the CWD pin to ground. This information can be found in the datasheet under section 8.3.2.2 Watchdog Enable Disable Operation.

Thanks,
Joshua
