Motor driver supports multiple control interface modes
Texas Instruments’ DRV8212 is an integrated motor driver with four N-channel power FETs, a charge pump regulator, and protection circuitry.
It is in stock at Digi-Key.
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.
It 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.
