説明
- TIDA-00771, 20A RMS Drive Reference Design for a 3-phase brushless DC (BLDC) motor in power tools operating from a 3-cell Li-ion battery with a voltage range of 5V to 12.6V. This design is a 45 x 50 mm compact drive implementing sensor-based trapezoidal control. The design uses a discrete, compact MOSFET-based three-phase inverter delivering 20A RMS continuous (70A peak for 1 second) winding current, without any external cooling or heat sink. The slew rate control and charge pump of the gate drive ensures maximum inverter efficiency (>97% at 10.8V DC) from 5V to 12.6V and optimum EMI performance
