This reference design demonstrates a dual motor drive solution for damper actuators and electronic expansion valves . The multiple motor drives include one bipolar stepper motor driver, one brushless DC motor driver, operating from a 15VDC source. The design shows accurate power limiting that helps for easy qualification as a low-power circuit, defined by IEC 60335-1. This reference design incorporates a 0-10V and 4-20mA control interface for controlling the position of the valve or damper, and a TMAG5273 which is used for accurate position sensing.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
