7.5. Reverse Connection Protection
This product protects the system by turning off the MOSFET when the power supply is reverse connected. The reverse connection detection circuit monitors the voltages at the VDD and GND terminals. When a reverse connection is detected, the reverse connection protection off-driver is activated, setting the voltage between the GATE and SOURCE terminals to a low level (VGSL), thereby turning off the MOSFET. Additionally, the GND switch is turned off to disconnect the internal GND wiring of the IC from the external GND, preventing reverse current from flowing into the IC through the GND terminal.
