SUMMARY
Controlling 5-10 IRF7739L1TRPBF power MOSFETs in parallel is feasible using a gate driver with a 5kHz motor PWM controller. The MIC4426, a two-channel gate driver, is recommended for this application. Various alternatives from Micrel, Texas Instruments, and Microchip are also available, providing multiple options for polarity and functionality. Refer to the respective datasheets for detailed specifications and compatibility.
