Part number: A3921
Manufacturer: Allegro
File Size: 1.12 MB
Datasheet: A3921-Allegro.pdf
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 sup

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 A3921 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor is used to provide the above-battery supply volta
