9.1.4 Reverse Current Blocking

Reverse current blocking is often desired in specific applications, as it prevents current from flowing from the output to the input of the load switch when the device is disabled. With the configuration illustrated in Figure 9-4, the TPS22976 can be converted into a single-channel switch with reverse current blocking. VIN1 or VIN2 can be used as the input and VIN2 or VIN1 as the output.
