10.8-V/30-W, >95% Efficiency, 4.3-cm2, Power Stage Reference Design for Brushless DC Servo Drive

TIDA-01587

Design files

Overview

This 15-W, 16-mm × 27-mm, power stage reference design drives and controls the position of the brushless DC (BLDC) motor operating from a three- to four-cell Li-ion battery. This highly-efficient solution is optimized with a very small form factor that easily fits into the motor and supports precise motor position control. The design is also capable of driving the motor at high speeds with position feedback. The reference design is protected for overcurrent and short circuit, and the onboard MCU provides UART connectivity, which enables controllability with any external controller.

Features
  • Brushless DC servo drive operates at voltage ranging from 6-V to 16.8-V (3 to 4 cell Li-ion battery)
  • Support 2.5 -ARMS continuous, 5-A peak motor winding current, with over current and shoot-through protection by VDS monitoring.
  • Closed loop 60° electrical position control with digital hall sensor feedback for a BLDC motor
  • Supports position control with sinusoidal excitation with analog hall feedback
  • Very small PCB form factor of 16mm x 27mm, with >95 % power stage efficiency
