Description
A3946 Half-Bridge Power MOSFET Controller .
Features
* ▪ On-chip charge pump for 7 V minimum input supply voltage ▪ High-current gate drive for driving a wide range of N‑channel MOSFETs ▪ Bootstrapped gate drive with top-off charge pump for 100% duty cycle ▪ Overtemperature protection ▪ Undervoltage protection ▪Applications
* that require high power unidirectional DC motors, three-phase brushless DC motors, or other inductive loads. 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 controlA3946 Distributors
