Another technical note from STMicroelectronics on fine tuning motor drivers for optimal thermal design. Link here (PDF)

One constant trend in the automotive world is the tendency to reduce the size of electronic components and the ECUs (Electronic Control Unit). While this development has many benefits for the car manufacturer as well as for the end customer, there are also challenges for the developers of these systems: especially for power drivers the design of robust applications requires an accurate estimation of the thermal power dissipation on a system level.

In this article a method to calculate the thermal power dissipation of a stepper motor driver is derived from a simple example to a model that includes the various configuration options and modes of a state of the art stepper driver, like that of ST Microelectronic’s L9942.
