The Allegro Microsystems A2918SWH is a dual full-bridge PWM motor driver capable of driving both windings of a bipolar stepper motor or bidirectionally controlling two DC motors. It supports a motor supply voltage of up to 45V and can deliver a continuous output current of ±1.5A. The device includes internal pulse-width modulation (PWM) control for precise output current regulation.
Key features include internal clamp and flyback diodes for protection against inductive transients, and internal thermal shutdown circuitry to prevent overheating. Internally generated delays prevent cross-over currents during direction switching. The A2918SWH is supplied in an 18-lead power-tab package and is available for operation from -40°C to +85°C.
This motor driver is suitable for applications requiring control of bipolar stepper motors or DC motors where precise current control and protection features are necessary. Its design simplifies power-up sequencing and provides robust operation.
