STMicroelectronics Automotive IC Evaluation Board for Daughter Board, Motherboard for L99H02QF DC Motor Control IC

The STMicroelectronics evaluation board designed for DC motor control IC in automotive applications. It is composed by a motherboard and a daughterboard on which the L99H02QF is pre-assembled. The motherboard, based on STM8A microcontroller, provides the logic section for monitoring and driving the L99H02QF assembled in the daughterboard. With the aim to make the board usage and settings simpler, ST provides a dedicated user-friendly software with a graphic user interface (GUI). This enables the user to set L99H02QF parameters and registers, simultaneously showing real time device diagnostic information like motor evolution, free-wheeling, board temperature and much more.
