A3946 Half-Bridge Power MOSFET Controller

A3946 Description

A3946 Half-Bridge Power MOSFET Controller .
The A3946 is designed specifically for applications that require high power unidirectional DC motors, three-phase brushless DC motors, or other induct.

A3946 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 ▪
* 40°C to 135°C ambient operatio

A3946 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 control
