Protection
While the source device should do most of the voltage regulation, TI recommends a transient-voltage suppressing diode be implemented on the VBUS_IN rail. The TVS2200 product is recommended within the PMIC’s datasheet.
TI additionally recommends a (Schottky) diode be placed from VBUS to ground. This is due to the possibility of large ground currents during sudden disconnects due to inductive effects in a cable. They recommend their TVS2200 product.
