Texas Instruments DRV8210 H-Bridge Motor Driver is an integrated motor driver with four N-channel power FETs, charge pump regulator, and protection circuitry. The tripler charge pump architecture allows the device to operate down to 1.65V to accommodate 1.8V supply rails and low-battery conditions. The charge pump integrates all capacitors to reduce the overall solution size of the motor driver on a PCB and allows for 100% duty cycle operation. The DRV8210 supports multiple 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 to achieve ultra-low quiescent current draw by shutting down most of the internal circuitry.
The device can supply up to 1.76A peak output current. It operates on a motor power supply voltage from 0 to 11V and a logic power supply voltage of 1.65V to 5.5V. The driver offers robust internal protection features include supply undervoltage lockout (UVLO), output overcurrent (OCP), and device overtemperature (TSD). The Texas Instruments DRV8210 is part of a family of devices which come in pin-to-pin, scalable RDS(on) and supply voltage options to support various loads and supply rails with minimal design changes.
