We’ve expanded our selection of motor drivers again with the release of some compact carrier boards for TI’s DRV8874 and DRV8876 motor drivers, which feature current sense feedback and adjustable current limiting. These three ICs and their boards are all very similar, differing mainly by the amount of current they can handle: in a TSSOP chip package, the DRV8874 delivers up to 2.1 A continuous on our carrier board and the DRV8876 does 1.3 A. The DRV8876 chip is also available in a smaller QFN package, so for a lower-current and lower-cost option, our DRV8876 (QFN) carrier can deliver 1.1 A continuously. All three versions can drive a single brushed DC motor at voltages from 4.5 V to 37 V.

The DRV8874 and DRV8876 drivers offer a choice of control modes that includes phase/enable (PH/EN) and direct PWM (IN/IN) as well as independent half-bridge control, which lets you drive two motors unidirectionally. With their wide operating voltage range and current sense/current limiting added in, this combination of capabilities results in some unusually versatile motor driver boards, especially considering their small size. (But if you need something that works with even higher voltages, consider our similar DRV8256E and DRV8256P carrier boards too, though those don’t provide current sense feedback.)
