The HIP2103-4DEMO1Z is a general purpose motor drive with a microprocessor controller. Three motor drive topologies are supported: 3-phase for BLDC motors, and full and half bridge for conventional brushed DC motors. Hall effect rotor position sensors are used to control the switching sequence of the BLDC topology (not required for the brushed DC motors). The operating bridge voltage can vary between 13V and 50V and the maximum motor current is 20 A (with sufficient airflow). 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 brushed or brushless DC motors are utilized. Because this demonstration board is primarily intended to highlight the application of the HIP2103 and HIP2104 3-phase MOSFET drivers with no specific motor 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 motor load dynamics.
