18-V: 2-A: 25-mm Brushed DC motor driver with stall detection and speed control reference design
Description
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.
Features
- Operates at voltages ranging from 4.5 V to 33.6 VHigh output peak current: 3.5 AIntegrated H-bridge pre-driver and FETsReliable motor stall detection by integrated current sensingOvercurrent: short circuit: overvoltage: undervoltage and thermal protectionsOperating ambient temperature: –40 °C to 85 °C
