The A4931GETTR-T from Allegro Microsystems is a comprehensive 3-phase brushless DC motor pre-driver designed to drive N-channel power MOSFETs. It supports motor supply voltages up to 30V, with one source indicating a range up to 37.5V.
Key features include fixed off-time PWM current control for limiting inrush current, locked-rotor protection with adjustable delay, thermal shutdown, and overvoltage monitoring. Synchronous rectification is integrated to reduce power dissipation.
The device utilizes three Hall-element inputs for commutation logic and provides FG1 and FG2 outputs for accurate motor rotation measurement. It is supplied in a 5 mm × 5 mm, 28-terminal QFN package with an exposed thermal pad, suitable for surface mounting.
Operating ambient temperature ranges from -20°C to 105°C, with an alternative range of -40°C to 105°C available. The maximum junction temperature is 150°C, and storage temperature ranges from -40°C to 150°C.
