STEVAL-IHM004V1 - Low Voltage Three-Phase BLDC/PMSM Motor Driver

The STEVAL-IHM004V1 from STMicroelectronics is a comprehensive evaluation platform designed to demonstrate the capabilities of ST's low voltage motor control solutions. This versatile board is ideal for driving three-phase brushless DC (BLDC) or permanent magnet synchronous motors (PMSM) that operate at voltages as low as 8V and up to 28V.

At the heart of the STEVAL-IHM004V1 is the advanced L6230 motor driver. This driver integrates a triple half-bridge able to drive the power MOSFETs with current sensing, under-voltage lockout, thermal shutdown features, and a non-dissipative overcurrent protection on the high side power MOSFETs. These features ensure the protection and longevity of your motor control applications.

The evaluation board is designed to be a user-friendly platform with multiple features that facilitate rapid development and testing. It includes a potentiometer for speed control, user buttons, and LEDs for direct interface and diagnostics. The board supports both sensor and sensorless motor control algorithms, making it adaptable to a wide range of applications.

Connectivity on the STEVAL-IHM004V1 is robust, with options for Hall sensor inputs and an encoder input for more precise control. Moreover, the board is equipped with a connector for an external power supply and has various test points for probing critical signals for in-depth analysis.

The STEVAL-IHM004V1 is supported by the STSW-IHM009M firmware package, which provides a rich set of motor control algorithms (including Field Oriented Control, 6-step sensorless control, and more) that can be used to jump-start your motor control projects.

Whether you are developing a prototype for a low voltage motor control application or simply exploring the features of ST's motor driver technology, the STEVAL-IHM004V1 evaluation board is an indispensable tool that combines performance, flexibility, and ease of use.
