    LED lights turn on and off. An alternative way of evaluating the TMAG5115 is by using the EVM to commutate a brushless direct current (BLDC) motor. The TMAG5115EVM follows a standard form factor for the Hall-effect sensor boards found in various NEMA17 BLDC motors.

    3-2). The EVM features three functionally independent circuits, one for each of the TMAG5115 devices on the PC board, with each sensor spaced 120° apart. The three sensors and the specific 120° spacing yield what is commonly referred to as a six-step commutation sequence, a common motor commutation algorithm for sensored motor control.
