The MP6539 is a gate driver IC designed for three-phase, brushless DC motor driver applications. The MP6539 is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 100V.
The MP6539 uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate driver if the output is held high for an extended period of time.
Full protection features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown.
The MP6539 is available in TSSOP-28 (9.7mmx6.4mm) and QFN-28 (4mmx5mm) packages with an exposed thermal pad.

The EV6539-V-00A is an evaluation board for the MP6539, a three-phase BLDC motor pre-driver.
It operates from a supply voltage of up to 100V. It is configured to drive 3 half bridges consisting of 6 N-channel Power MOSFETs. The rotor position information is provided by the Hall sensors assembled in the motor and the driving control signals are generated by the external controller, such as MCU, FPGA, etc.
