This slideshare shows everything what has to do with Cordless Power Tools like drilling machines - from the technical point of view, of course. So learn how an integrated BLDC motor drive board looks like and works with its OptiMOS 1 mOhm 40V 3-phase inverter. Learn how the software development tool chain DAVE will help to implement the right code onto Infineon XMC1300 microcontroller. And get to know the benefits of integrated Schottky-like diode of BSC010N04LSI.
