Overview
The DRV8210DSGR is an integrated motor driver from Texas Instruments, designed to drive brushed DC motors and other resistive, inductive, or LED loads. This device features four N-channel power FETs, a charge pump regulator, and comprehensive protection circuitry. The tripler charge pump architecture allows the device to operate down to 1.65 V, making it suitable for applications with low-battery conditions or 1.8-V supply rails. The DRV8210DSGR supports multiple control interface modes, including PWM, phase/enable, independent half-bridge, and parallel half-bridge, each with a low-power sleep mode to minimize quiescent current draw.
