18-V, 2-A, 25-mm Brushed DC motor driver with stall detection and speed control reference design
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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
