Magnetic Speed Sensor ICs

Allegro MicroSystems Magnetic Speed Sensor ICs offer a comprehensive portfolio covering the full range of speed and speed with direction sensor ICs. These products include a two- and three-wire interface, a magnetic encoder (ring magnet) and gear tooth sensing, Hall and GMR technology, and ASIL-compliant options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications.

Brushless DC Drivers

Allegro MicroSystems Brushless DC Drivers (BLDC) are engineered to meet demanding market challenges, delivering cost-optimized systems and improved time-to-market while maintaining quality. The integrated MOSFET and gate driver ICs provide superior performance for automotive, industrial, and consumer applications, ranging from 3.5V to 100V operating voltage.

Motor Drivers

Allegro MicroSystems Motor Drivers offer robustness and safety, delivering superior performance in harsh, high voltage environments. These durable drivers enable motors to run more quietly, efficiently, and reliably. The embedded motion control algorithms simplify designs while improving motor performance and time-to-market. The Allegro MicroSystems Motor Driver portfolio includes brushless DC drivers, brush DC drivers, and stepper drivers for automotive, industrial, and consumer applications.

A4931 Three-Phase DC Motor Pre-Driver

Allegro MicroSystems A4931 Three-Phase DC Motor Pre-Driver can drive a wide range of N-channel power MOSFETs and supports motor supply voltage up to 30V. The A4931 pre-driver features fixed off-time pulse-width modulation (PWM) current control for limiting inrush current, thermal shutdown, locked-rotor protection with adjustable delay, overvoltage monitor, and synchronous rectification. The internal synchronous rectification reduces power dissipation by turning on the appropriate MOSFETs during current decay, shortening the body diode with the low RDS(on) MOSFET. Synchronous rectification is disabled by the overvoltage protection when the motor pumps the supply voltage beyond the overvoltage threshold during current recirculation. This pre-driver offers direction, enable, and brake inputs that can control current using either phase or enable chopping, and the logic outputs FG1 and FG2 can be used to measure motor rotation accurately. Allegro MicroSystems A4931 Three-Phase DC Motor Pre-Driver is available in a 5mm x 5mm, 28-terminal QFN package with an exposed thermal pad.
