Frequently asked questions
Can I drive the IRF7309 directly from a 3.3 V or 5 V microcontroller pin?
The IRF7309 is designed for logic-level gate drive, but the on-resistance depends on gate voltage. Check the datasheet RDS(on) value at the gate voltage you will use (for example 4.5 V or 10 V) before relying on it, and use a gate resistor for stable switching.
How do I wire the N-channel and P-channel sections?
The N-channel section is typically used as a low-side switch, with the load between the supply and the drain and the source to ground. The P-channel section is typically used as a high-side switch, with the source connected to the positive supply and the load on the drain. Confirm the pinout in the datasheet before wiring.
