Description
The A4957 is a full-bridge controller for use with external N-channel power MOSFETs and is specifically designed for 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
▪4.5 to 50 V supply voltage range
▪Diagnostics output
▪Low current sleep mode
