DRV8212 Low-Voltage H-Bridge Motor Driver

Texas Instruments' 11 V, 2 A driver features PWM, PH/EN, and half-bridge control interfaces

Image of Texas Instruments' DRV8212 Low Voltage H-Bridge Motor DriverTexas Instruments' DRV8212 is an integrated motor driver with four N-channel power FETs, a charge pump regulator, and protection circuitry. The triple-charge pump architecture allows the device to operate down to 1.65 V to accommodate the 1.8 V supply rails and low-battery conditions. The charge pump integrates the capacitors to reduce the overall solution size of the motor driver on a PCB and allows for 100% duty-cycle operation. The DRV8212 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 4 A peak output current. It operates with a supply voltage from 1.65 V to 5.5 V. The driver offers robust internal protection features including supply undervoltage lockout (UVLO), output overcurrent (OCP), and device overtemperature (TSD). The DRV8212 come in pin-to-pin scalable RDS(ON) and supply voltage options to support various loads and supply rails with minimal design changes.
