H-Bridge brushed and stepper motor control solution
Description
This reference design demonstrates a motor control solution for spinning three-phase brushed DC or single stepper motor - featuring the C2000™ Piccolo™ microcontroller and the DRV8412 three-phase motor driver. This highly integrated: robust motor control and driver solution speeds development time for brushed and stepper motors running up to 6 A continuous / 12 A peak at 50 V. Typical applications include medical pumps: gate openers: stage lighting: textile manufacturing tools: and industrial or consumer robotics. This reference design is based on the DRV8412 evaluation kit.
Features
- High-efficiency power stage (up to 97%) with low RDS(on) MOSFETs (110 mΩ at TJ = 25 °C) Operating supply voltage up to 52 VIntegrated self-protection circuits including undervoltage: over-temperature: overload: and short circuitClosed-loop digital control with feedback using the C2000’s on-chip PWM and ADC peripheralsHigh precision low-side current sensing using the C2000’s high-performance ADC: Texas Instruments OPA2350 high speed op-amps and Texas Instrument REF3025 high precision voltage reference chipFully-functional evaluation board includes software: hardware design files: quick start graphical interface: and step-by-step documentationNOTE: Software for this board can be found inside the controlSUITE™ software package.
