The TIDA-01330 reference design implements the drive circuits for two independent brushed DC motors. It provides a solution for automotive power seats with a highly integrated 2-axis driver, reducing the overall bill of materials. The interface to a simple microcontroller Illustrates how the design reduces the processing burden on the control software. In addition to the drive circuit for two motors, this design also includes current feedback sense circuits and other diagnostic features to ensure reliable operation and detection of faults. The control circuit for an LED illumination element is included, as well as the ability to provide tactile feedback to the seat occupant by vibrating in either axis.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
