Description

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.
