A3922 - Automotive Full-Bridge MOSFET Driver

General 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.

Key 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.
