Integrated current sensing H-bridge motor driver with 50-V, 3.6-A capability

DRV8871DDAR General Description

Featuring advanced current-regulation circuitry, the DRV8871DDAR sets itself apart by eliminating the need for an analog voltage reference or external sense resistor. Instead, a standard low-cost resistor is utilized to adjust the current threshold, resulting in more efficient power utilization and reduced system requirements. This innovative approach not only enhances overall system stability but also minimizes the need for bulk capacitance during motor startup and stall conditions
