STMicroelectronics in collaboration with MikroElektronika are creating four “Click boards” to extend STSPIN motor drivers for STM32-based designs to users of MikroElektronika prototyping boards, as well as other systems containing a mikroBUS socket. The devices integrate advanced control features, a protected output stage, and safety functions including non-dissipative over-current protection in a small footprint. Mounted on the plug-and-play click boards, the motor drivers are ready to use without any hardware configuration.

The STSPIN220 Click board contains the STSPIN220 IC, a 10V stepper driver with 256-microstep resolution. Delivered in a 3mm x 3mm QFN package, it has a standby current of 10nA (typical) and can deliver up to 1.3A to drive the motor with PWM current control through each of the two on-chip 0.4Ω H-bridges. The board also features the 3mm x 3mm STSPIN250 high-current DC brush motor driver, suitable for motor voltages from 1.8V to 10V and capable of supplying up to 2.6A through 0.2Ω on-resistance H-bridges, with a standby current of 10nA (typical).

Along with the 3mm x 3mm STSPIN233, which contains three half bridges with independent input and enable pins and supports 3-shunt sensing, the board is ready for 1.8V-10V motor operation. Three STSPIN Click boards are available now and the STSPIN233 version will follow later in Q4 2019, all priced from $14.00 each.
