The Texas Instruments DRV8210 H-bridge Motor Driver is an integrated motor driver featuring four N-channel power field effect tubes, charge pump regulators and protection circuits. The treble charging pump structure allows the device to operate below 1.65V to accommodate the 1.8V powered track and low battery conditions. The charge pump integrates all capacitors to reduce the overall solution size of the motor driver on the PCB and allow 100% duty cycle operation.

     The DRV8210 supports a variety of control interface modes, including PWM (IN1/IN2), phase/enable (PH/EN), independent half-bridge and parallel half-bridge. Each interface supports a low-power sleep mode, enabling ultra-low static current by shutting down most of the internal circuitry.

     The device provides A peak output current of up to 1.76A. It operates at 0 to 11V motor supply voltage and 1.65V to 5.5V logic supply voltage. The drive provides powerful internal protection features, including power undervoltage lock (UVLO), output overcurrent (OCP), and device overtemperature (TSD). The Texas Instruments DRV8210 is part of a family of devices that feature pin-to-pin, expandable RDS(on) and supply voltage options to support a variety of loads and supply rails with minimal design changes.
