ZHCSI09S June 2010 – August 2018 TPS65911
The PWRDN input is a reset input with selectable polarity (PWRDN_POL). High(low) level at input forces the TPS65911 device into off mode, causing a power-off reset. Off mode is maintained until PWRDN is released and a start-up reason (for example, PWRON button press or DEV_ON = 1) is detected. An interrupt is generated to indicate the cause for shutdown. The PWRDN input is in the VRTC domain but can tolerate a 5-V input.
