Allegro MicroSystems AMT49105
The AMT49105 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a three-phase bridge arrangement and is specifically designed for automotive applications with high-power inductive loads such as BLDC motors. The AMT49105 is designed to provide the gate drive, supply, and peripheral functions in a system where a small microcontroller provides the motor control, communication interface to a central ECU and intelligent fault and status handling. The AMT49105 provides the supply and watchdog for the microcontroller and the high voltage interfaces between the microcontroller and the central ECU and ignition switch.
