The STSPIN250 for brushed DC motors integrates a MOSFET full-bridge and a fixed off-time PWM current controller in a tiny 3mm x 3mm QFN package. Operating from a supply voltage as low as 1.8V, it helps the designer to save power thanks to its best-in-class stand-by current of <80nA.
Offering a maximum output current up to 2.6Arms, it may be used in low- and medium-power applications.
The STSPIN250 is supplied with ST’s STSW-SPIN002 evaluation software. This SPIN family tool is a software package for PCs based on the Windows® operating environment.
A command section enables control of a stepper or brushed DC motor. Device configuration can be performed through a registry editor, a user-friendly configuration panel or a wizard. The wizard contains pre-defined configurations for demonstration boards.
Configurations can be stored and loaded.
A script editor enables the user to control all aspects of the device by implementing commands written in the Python language.
