The IRL1004PBF specifies a maximum gate charge of 100 nC at 4.5 V, with the Rds(on) characterised at both 4.5 V and 10 V drive voltages. At a 100 kHz switching frequency, the 100 nC gate charge draws about 10 mA from the driver — a figure that fits within the output capability of most standard gate-driver ICs, but the designer should verify the driver's peak current and average power dissipation for the target switching rate. The 6.5 mOhm Rds(on) is specified at 10 V drive; at 4.5 V the on-resistance will be higher, so the 10 V rail is preferred for minimum conduction loss.
Thermal and temperature range — the junction budget
The 200 W maximum power dissipation at case temperature is a package-limited figure; the real thermal budget depends on the heatsink and airflow, and the 130 A continuous rating requires a case temperature held at 25°C — derate aggressively above that.
