A4957 - Full Bridge MOSFET Driver

A4957 Description

A4957 Full Bridge MOSFET Driver .
The A4957 is a full-bridge controller for use with external N-channel power MOSFETs and is specifically designed for applications with high-power indu.

A4957 Features

* ▪ 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 PACKAGE: 24-contact

A4957 Applications

* with high-power inductive loads such as brush DC motors. A unique charge pump regulator provides full ( >10 V ) gate drive for battery voltages down to 7 V and allows the A4957 to operate with a reduced gate drive, down to 4.5 V. A bootstrap capacitor is used to provide the above battery supply volt
