Full-Bridge Power MOSFET Controller

The A3940KLP and A3940KLW are designed specifically for automotive applications that require high-power motors. Each provides four high-current Gate drive outputs capable of driving a wide range of n-channel power MOSFETs in a full-bridge configuration.
Bootstrap capacitors are utilized to provide the above-battery supply voltage required for n-channel FETs An internal Charge Pump for the high side allows for dc (100% duty cycle) operation of the bridge.
Protection features include supply under/overvoltage, thermal shutdown, and motor lead short-to-battery and short-to-ground fault notification, and a programmable dead-time adjustment for crossconduction prevention. The overvoltage trip point is user adjustable.
