The A3938SLD is a brushless DC (BLDC) motor controller and driver from Allegro Microsystems. It integrates commutation and direction management functions, making it suitable for controlling the speed and direction of BLDC motors.
Electrically, the device operates from a supply voltage of 18V to 50V. It provides three pre-driver half-bridge outputs using Power MOSFET technology. The interface supports both parallel and PWM control signals, offering flexibility in system integration.
The A3938SLD is available in a 38-TSSOP (also 38-TFSOP) surface mount package. It is designed for surface mount assembly and operates over an ambient temperature range of -20°C to 85°C.
This motor driver is intended for general purpose motor control applications, including industrial, automotive, and consumer systems where BLDC motor commutation and direction management are required.
