ST collaborates with Microelectronica
STSPIN Announces 4 Motor Drive Click Boards


STMicroelectronics announced on the 17th that it has developed four types of Click boards in collaboration with its partner, MikroElektronika.

The four STSPIN Click boards allow STSPIN motor drivers to be applied not only to STM32-based designs but also to Microelectronica's prototype boards and systems equipped with 'mikroBUS' sockets.

STSPIN ICs simplify motor control by integrating advanced control functions and safety features, such as output protection and non-dissipative overcurrent protection, into an ultra-small footprint. The motor driver stacked on the new plug-and-play click board can be used immediately without any hardware configuration.

ST has supported the development of MikroSDK libraries and code examples in partnership with Microelectronics to provide high-performance software that enables users to make the most of each board's capabilities.

The STSPIN220 features the 'STSPIN220 IC', a 10V stepper driver that provides 256-level microstepping resolution. It is supplied in a 3×3mm QFN package and supports a minimum standby current of 10nA and supplies up to 1.3A, allowing it to drive motors with PWM current control via two 0.4Ω H-bridges on the chip.

STSPIN820 provides cost-effectiveness for 7 to 45V applications by supporting up to 1.5A with 256-level microstepping resolution and a 4×4mm QFN.

The STSPIN250 features the 'STSPIN250 IC', a 3×3mm high-current DC brushed motor driver. It is suitable for motor voltages of 1.8 to 10V and can supply up to 2.6A through a 0.2Ω on-resistance H-bridge. The standby current is 10nA.

The STSPIN233 click board for BLDC motor drives features a 3×3mm 'STSPIN233 IC', includes three half-bridges with independent input and enable pins, and supports three shunt detection functions. STSPIN233, suitable for 1.8~10V motor operation, supports a standby current of 10nA.

STSPIN drivers, supporting low motor voltage capabilities, low resistance MOSFETs, low standby current, and ultra-small packages, extend battery life and save space in portable and mobile applications, as well as other battery-powered applications such as smartphone pop-up cameras, gimbals, healthcare products, small appliances, toys, POS terminals, robots, drones, electronic locks, and valves.

STSPIN motor drivers, currently supplied as click board modules, are part of an add-on board standard and ecosystem featuring over 700 click boards. This ecosystem supports all users, from professional engineers to manufacturers and hobby developers, in applying motor control capabilities to their projects.

The STSPIN Click Board is currently available for purchase, and the STSPIN233 version is scheduled for release in the fourth quarter of 2019. Prices for each Click Board start at $14.
