Brushed DC motor driver with integrated current sensing saves power for 12- and 24-V motors
- Reduced system complexity: When designing with the DRV8871, the elimination of discrete sense resistors reduces board space by up to 25 percent.
- Optimal power consumption: The devices use standard low-cost, low-power resistors to set the current threshold, limiting startup and stall inrush currents. The ability to limit current to a known level can significantly reduce the system power requirements and bulk capacitance needed to maintain a stable voltage, especially for motor startup and stall conditions.
- Simplified design: Board layout with accurate current regulation is simplified because no sense routing is required with the DRV8871.
- Wide supply range: The devices offer a wide 6.5- to 45-V motor-supply voltage to support industry-standard 12- and 24-V supplies.
