AMT49502 Datasheet 80v Automotive Half-bridge MOSFET Driver

Manufacturer: Allegro MicroSystems

Overview: AMT49502 80 V Automotive Half-Bridge MOSFET Driver.

General Description

The AMT49502 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a half-bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors, BLDC motors, VR/SR motors, solenoids, and actuators.

A unique charge pump regulator provides full gate drive over the full supply voltage range from 5.5 to 80 V for most applications.

A bootstrap capacitor is used to provide the above-battery supply voltage required for N-channel MOSFETs.

Key Features

  • Half-bridge MOSFET driver.
  • Bootstrap gate drive for N-channel MOSFET bridge.
  • Independent control of high-side and low-side gate drives with cross-conduction capability.
  • Charge pump regulator for low supply voltage operation.
  • 5.5 to 80 V supply voltage operating range.
  • Integrated logic I/O supply.
  • SPI-compatible serial interface.
  • Bridge control by direct logic inputs or serial interface.
  • Programmable gate.
