Users Manual HIP4086DEMO1Z Users Manual: Demonstration Board Industrial Analog and Power All information contained in these materials, including products and product specifications, represents information on the product at the time of publication and is subject to change by Renesas Electronics Corp. without notice. Please review the latest information published by Renesas Electronics Corp. through various means, including the Renesas Electronics Corp. website ( Users Manual HIP4086DEMO1Z Demonstration Board The HIP4086DEMO1Z is a general purpose 3-phase BLDC motor drive with a microprocessor based controller. Hall effect shaft position sensors control the switching sequence of the three 1/2 bridge outputs. The bridge voltage can vary between 12V and 60V and the maximum summed bridge current is 20A (with sufficient air flow). This motor drive can be used as a design reference for multiple applications including e-bikes, battery powered tools, electric power steering, wheel chairs, or any other application where a BLDC motor is used. Because this demonstration board is primarily intended to highlight the application of the HIP4086 3-phase MOSFET driver with no specific application targeted, the control features are limited to simple functions, such as start/stop, reverse rotation, and braking. Open-loop speed control is implemented. More advanced control features, such as torque control, speed regulation, and regenerative braking are not implemented because these methods require close integration with the characteristics of the load dynamics. This user manual covers the design details of the HIP4086DEMO1Z with a focus on the design implementation of the HIP4086 driver using recommended support circuits. This guide also covers the design method of the bipolar current sensing feature. Presently, current sensing on this demonstration board is used only for pulse-by-pulse current limiting. However, an analog signal proportional to the motor current is available on board as a design reference. The microcontroller firmware is also provided as a reference but the only support offered by Renesas is for bug corrections and for adding more switching sequences. See Microchip for details on the PIC18F2431 usage.

See the sequence charts in Selecting the Correct Switching Sequence on page 17 to verify that your desired sequence is implemented. If you require a different sequence for your specific motor application or if you need help identifying the correct switching sequence for your specific motor, please contact Renesas prior to ordering this demonstration board for possible support for a new switching sequence.
