Beschreibung

This reference design demonstrates a 1.5-kW power stage for driving a three-phase brushless DC motor in cordless tools operating from a 15-cell Li-ion battery with a voltage up to 63-V. The design is a 70mm x 69mm compact drive, bringing 25-ARMS continuous current at 20-kHz switching frequency without heat sink and with natural convection, implementing sensorbased trapezoidal control. The design achieves optimized MOSFET switching loss and EMI by using a smart gate driver with optimized MOSFET and PCB. The design shows MOSFET operation within the safe operating area using enhanced protections including MOSFET over current and shoot-through protection by VDS monitoring, gate protection, switching voltage spike optimization with slew rate control and over temperature protection.
