A4931METTR-T ALLEGRO Power MOSFET
The A4931METTR-T from Allegro MicroSystems is a 3‑phase brushless DC motor pre‑driver that simplifies BLDC control with integrated Hall commutation, PWM current control, and synchronous rectification for low power dissipation. For selection, it operates from 8V to 37.5V, supports external N‑channel MOSFETs, and features locked‑rotor protection with adjustable delay, overvoltage monitoring, thermal shutdown, and FG speed outputs. In application, it excels in automotive systems such as electric power steering, engine cooling fans, fuel pumps, and HVAC blowers; industrial pumps and fans; robotics; power tools; and home appliances where reliable, efficient 3‑phase motor drive with comprehensive fault protection is essential in a compact 28‑QFN (5x5mm) package.
