8.4 Device Functional Modes

The LM74810-Q1 enters shutdown mode when the EN/UVLO pin voltage is below the specified input low threshold V(ENF). Both the gate drivers and the charge pump are disabled in shutdown mode. During shutdown mode the LM74810-Q1 enters low IQ operation with a total input quiescent consumption of 2.87 μA (typ). When the LM74810-Q1 is in shutdown mode, forward current flow to always ON loads connected to the common drain point of the back to back MOSFETs is not interrupted but is conducted through the MOSFET's body diode.
