EV6543-L-01A

EV6543-L-01A 3V to 12V, Three-Phase Brushless DC Motor Driver Evaluation Board DESCRIPTION FEATURES The EV6543-L-01A is an evaluation board for the MP6543GL, a three-phase, brushless DC motor driver.    The EV6543-L-01A operates from a maximum 12V supply voltage. It integrates three halfbridges consisting of six 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 an MCU or FPGA.

Attach the input voltage (3V ≤ VIN ≤ 12V) to the VIN connector, and attach the input ground to the GND connector. 2. Attach the LDO input voltage (3V ≤ VIN_LDO ≤ 12V) to the VIN_LDO connector, and attach the input ground to the GND connector. 3. Attach a 3.3V constant voltage to the VCC connector, then switch SW1 to position 1 (top side) to enable the chip. 4. To set the current-sense output reference voltage, attach a 3.3V constant voltage to the VREF connector. 5. Attach the motor’s Hall signals to the Hall sensor connector. 6. Attach the driving control signals (generated by the external controller) to the CN1 connector. EV6543-L-01A Rev. 1.0 MonolithicPower.com 11/20/2020 MPS Proprietary Information. Patent Protected.
