Q: Enabling / Disabling Watchdog function in TPS3823-33 by 1136393
Hi,Would like to know how we can enable/disable watchdog function in TPS3823-33 device. Customer would like to enable watchdog function through MCU GPIO and then when not required, he needs to disable the watchdog function. By making the PIN WDI to open/close will disable/enable the watchdog function.

Per the TPS3823-33 datasheet, "Leaving WDI unconnected disables the watchdog". You can use your uP with open, or tri-stated GPIO to disable the watchdog. To enable watchdog ( WDI ), simply configure the GPIO to drive a logic high and low to the WDI pin.
