Texas Instruments has introduced 70W brushless dc motor drivers with code-free sensor-less ield-oriented or trapezoidal control. In common, the devices include a set of commutation control algorithms which manage functions such as motor fault detection and protection mechanisms. Operation is from 4.5 to 35V (40V abs max) and the 95mΩ output drivers (high-side plus low-side 25°C) ...
