Insulated control terminal that must be charged and discharged.
Use a gate driver, series resistor and gate-to-source pull-down.
Threshold is 2–4 V at only 250 µA. The 8 mΩ maximum on-resistance is specified at 10 V gate drive and 62 A, not at 3.3 V logic.
Connects to the controlled load in a low-side N-channel switch.
Place the load between its positive supply and drain pin 2.
The exposed metal tab is drain. The body diode has its cathode at drain.
Return terminal and reference for gate voltage.
Connect to common ground in the pictured low-side circuit.
The body diode has its anode at source. Keep the driver return close to this terminal.
