18-V/400-W 98% Efficient Compact Brushless DC Motor Drive w/Stall Current Limit Reference Design (TIDA-00772)

The TIDA-00772 is a 18 A RMS drive for a three phase brushless DC (BLDC) motor in power tools operating from a 5-cell Li-ion battery with a voltage up to 21 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 18 A RMS continuous (60 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 (>98% at 18V DC) 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 flexible mounting of board, high efficiency brings more battery duration and the 60 A peak current capability provides high momentary peak torque in power tools.
