Description
A4940 Automotive Full-Bridge MOSFET Driver .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 ▪ 5.5 to 50 V supply voltage range ▪ Diagnostics output ▪ Low current sleep mode PACKAGE: 24-pin TSSOApplications
* 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 A4940 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor is used to provide the above battery supply voltA4940 Distributors
