For overvoltage protection, device turns on the FET as VOVP falls below VOVPF

8.4 Device Functional Modes

The device can be brought into low power shutdown mode by bringing the EN/SHDN pin low. In low power

shutdown mode, the internal blocks of devices are shut down and it takes IQSD from VCC supply. See the Enable

and Shutdown Input (EN/SHDN) section for details.
