Overview
The DRV8220DRLR is an integrated motor driver produced by Texas Instruments. It features four N-channel power FETs, a charge pump regulator, and comprehensive protection circuitry. This device is designed to drive one bidirectional brushed DC motor, two unidirectional brushed DC motors, or other loads such as single- or dual-coil latching relays, push-pull and bistable solenoids, and various resistive, inductive, or LED loads. The DRV8220 operates within a supply voltage range of 4.5 to 18 volts and supports multiple control interface modes, including PWM, phase/enable, independent half-bridge, and parallel half-bridge configurations.
