The device features a high voltage drive pin (DRV1) to support an input or output disconnect FET. This in can be also used as a driver for a charge pump output to do a reverse polarity protection using a external n-channel FET. The supply for this pin can be selected by R2D and I2C configurations.
The following configurations are possible with to support with the DRV1 pin:
The sequencing of the DRV pin is depending on the R2D/I2C setting an given by the state diagram XREF
