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
