AN75813 - H Bridge Based Motor Drive Protection Using PSoC® 3
H-Bridge driven DC motors are widely used in many automotive applications such as HVAC, power seats, wipers, and power windows. It is important to protect the motor drive system, because failure to do so may result in damaged components and, in some cases, hazardous conditions. In this application note, we discuss a novel approach to fault detection and protection where, instead of using pre-packaged motor drivers with built-in protection systems, we use basic components such as FETs and gate drivers. This method results in a larger number of available test signals and hence better determination of fault conditions. Combined with the configurability of PSoC 3 devices, this method also leads to a scalable and programmable system that can be easily shared across multiple H-Bridges.
