What is a Brushless DC motor driver?

A brushless DC motor driver is a semiconductor device that drives and controls a motor according to instructions from a control unit such as a microcomputer. Control of a brushless DC motor is very complicated, so it is possible to create a drive circuit with discrete semiconductor parts, but the number of parts increases and software control becomes more complicated. Therefore, motor drivers are often used to reduce the software development load and the number of parts.
