Datasheet Details

Part number:

A3941

Manufacturer:

Allegro

File Size:

1.05 MB

Description:

Automotive Full Bridge MOSFET Driver

Features

* ▪ High current gate drive for N-channel MOSFET full bridge ▪ High-side or low-side PWM switching ▪ Charge pump for low supply voltage operation ▪ Top-off charge pump for 100% PWM ▪ Cross-conduction protection with adjustable dead time ▪ 5.5 to 50 V supply voltage range ▪ Integrated 5 V regulator ▪ D

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 A3941 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor is used to provide the above-battery supply volta
