Four Click boards simplify motor control
STMicroelectronics and MikroElektronika have collaborated to create four Click boards based on STSpin Modules. They are designed for STM32-based motor controller designs, users of MikroElektronika prototyping boards and other systems containing a mikroBUS socket.
ST’s STSpin ICs integrate advanced control features, 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, explains ST. The company has worked with MikroElektronika to support the creation of MikroSDK software development kit libraries and code examples.
The STSPIN220 Click board contains the STSPIN220 IC, which is the market’s first 10V stepper driver with the 256-microstep resolution, says ST. It is delivered in a 3.0 x 3.0mm QFN package. According to the company, it has the market’s lowest standby current, at 10nA (typical), and can deliver up to 1.3A to drive the motor with PWM current control through each of the two on-chip 0.4 Ohm H-bridges.
The STSPIN820 Click board with the STSPIN820 stepper driver delivers an optimal balance of cost and performance for 7.0 to 45V applications, with the 256-microstep resolution and delivering up to 1.5A in a 4.0 x 4.0mm QFN.
The STSPIN250 Click board features the 3.0 x 3.0mm STSPIN250, claimed to be the smallest high-current DC brush motor driver in the market. Suitable for motor voltages from 1.8V to 10V and capable of supplying up to 2.6A through 0.2 Ohm on-resistance H-bridges, it also has extremely low standby current of just 10nA (typical).
The STSPIN233 Click board for brushless DC (BLDC) motor drives features the 3.0 x 3.0mm STSPIN233, which contains three half bridges with independent input and enable pins and supports three-shunt sensing. Ready for 1.8 to 10V motor operation, the STSPIN233 has low standby current of 10nA (typical) and is supplied in a compact 3.0 x 3.0mm QFN outline.
STSpin drivers have low motor-voltage capabilities, energy-efficient low-resistance MOSFETs, extremely low standby current and a small outline to ensure longer battery life and save space in portable, mobile, and other battery-powered applications, such as smartphone pop-up cameras, healthcare products, robots or drones.
Three STSPIN Click boards are available now and the STSPIN233 version will follow later in Q4 2019.
