18-V, 2-A, 25-mm Brushed DC motor driver with stall detection and speed control reference design


Design files


This reference design demonstrates a brushed DC (BDC) motor driver solution for a vacuum robot main wheel and main brush, which can detect a motor stall without any additional sensors. This design allows for a low component count and small form factor while providing flexibility for controlling BDC motors. The design incorporates enhanced protections like overcurrent, overvoltage, undervoltage and thermal shutdown.

  • Operates at voltages ranging from 4.5 V to 33.6 V
  • High output peak current: 3.5 A
  • Integrated H-bridge pre-driver and FETs
  • Reliable motor stall detection by integrated current sensing
  • Overcurrent, short circuit, overvoltage, undervoltage and thermal protections
  • Operating ambient temperature: –40°C to 85°C
