AMT49106 Datasheet Automotive Three-phase MOSFET Driver

Manufacturer: Allegro MicroSystems

Overview: AMT49106 Automotive Three-Phase MOSFET Driver.

General Description

The AMT49106 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a 3-phase bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as BLDC motors.

A unique charge pump regulator provides the supply for the MOSFET gate drive for battery voltages down to 5.5 V and allows the AMT49106 to operate with a reduced gate drive down to 4.5 V.

Gate drive voltage and strength are programmable to help reduce EMC issues.

Key Features

  • 3-phase 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.
  • Strong VREG charge pump to support up to 40 mA average gate switching current, enables driving 330 nC external MOSFETs at 20 kHz.
  • Operation at any PWM duty cycle up to and including 100%.
  • 4.5 to 50 V supply voltage operating range.
  • Supp.
