10.8V/20A RMS, 97% Efficient, Compact Drive for BLDC Motor with Stall Current Limit Reference Design (TIDA-00771)

The TIDA-00771 is a 20 A RMS drive for a three phase brushless DC (BLDC) motor in power tools operating from a 3-cell Li-ion battery with a voltage range of 5 V to 12.6 V. 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 20 A RMS continuous (70 A 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 5 V to 12.6 V and optimum EMI performance. The cycle-by-cycle overcurrent protection feature protects the power stage from large stall currents and the board can work up to 55°C ambient. The small form factor enables placement of board close to the battery pack, high efficiency brings more battery duration and the 70 A peak current capability provides high momentary peak torque in power tools.
