A4940LP Datasheet PDF - Allegro MicroSystems

Description
The A4940 is a full-bridge controller for use with external N-channel power MOSFETs and is specifically designed for automotive applications with high-power inductive loads such as brush DC motors.

FEATUREs and Benefits
▪ High current gate drive for N-channel MOSFET full bridge
▪ Independent control of each MOSFET
▪ Charge pump for low supply voltage operation
▪ Cross-conduction protection with adjustable dead time
▪ 5.5 to 50 V supply voltage range
▪ Diagnostics output
▪ Low current sleep mode
