Seven low-side channels for multi-coil loads
The DRV777PWR is a fully integrated motor driver from Texas Instruments that packs the control logic and power stage into a single 16-TSSOP package. It drives brushed DC motors and unipolar stepper motors using seven NMOS low-side outputs, each rated for 1 A continuous.
Supply and load voltage range
Both the logic supply and the motor load voltage share a common 5 V to 20 V range, simplifying the power rail design to a single regulated bus. The parallel interface accepts standard logic-level commands without a separate VIO pin. The seven low-side outputs let the driver sink current from multiple motor windings or solenoids independently. For a unipolar stepper, four outputs handle the two center-tapped coils; the remaining three channels can drive additional loads such as brakes or indicators.
The 16-TSSOP body (4.40 mm width) fits compact PCB layouts where board area is at a premium.
