AMT49100 Datasheet 80v Automotive Three-phase MOSFET Driver

Manufacturer: Allegro MicroSystems

Overview: AMT49100 80 V Automotive Three-Phase MOSFET Driver.

General Description

The AMT49100 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a 3-phase bridge arrangement and is specifically designed for 48 V automotive power applications with high-power inductive loads, such as BLDC motors.

A fixed-frequency buck converter provides a regulated gate drive and bootstrap charge voltage over the full supply voltage range from 10 to 80 V.

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

Key Features

  • 3-phase bridge MOSFET driver.
  • Bootstrap gate drive for N-channel MOSFET bridge.
  • Cross-conduction protection with adjustable dead time.
  • Fixed-frequency buck converter.
  • Operation at any PWM duty cycle up to and including 100%.
  • Programmable gate drive strength.
  • 10 to 80 V supply voltage operating range.
  • Programmable 3.3 or 5 V CMOS compatible logic I/O.
  • Three programmable current sense amplifiers.
  • S.
