Description
The A3922 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a full-bridge (H-bridge) arrangement and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors solenoids and actuators.
Features
- Full-bridge MOSFET driver.
- Bootstrap gate drive for N-channel MOSFET bridge.
- Cross-conduction protection with adjustable dead time.
- Charge pump for low supply voltage operation.
- Programmable gate drive voltage.
- 5.5 to 50 V supply voltage operating range.
- Integrated current sense amplifier.
- SPI compatible serial interface.
- Bridge control by direct logic inputs or serial interface.
- TTL-compatible logic input.
