3946 Description
The A3946 provides two high-current gate drive outputs that are capable of driving a wide range of power N-channel MOSFETs. The high-side gate driver switches an N-channel MOSFET that controls current to the load, while the low-side gate driver switches an N-channel MOSFET as a synchronous rectifier. A bootstrap capacitor provides the above-battery supply voltage required for N-channel MOSFETs.
