ZHCSHV4G October 2017 – December 2020 LM74700-Q1
PRODMIX
For the LM74700-Q1 to operate in reverse current protection mode, the gate driver must be enabled as described in the Gate Driver section and the current of the external MOSFET must be flowing from the drain to the source. When the ANODE to CATHODE voltage is typically less than –11 mV, reverse current protection mode is entered and the GATE pin is internally connected to the ANODE pin. The connection of the GATE to ANODE pin disables the external MOSFET. The body diode of the MOSFET blocks any reverse current from flowing from the drain to source.
