ST puts motor drivers into Click board format for hardware development
The development PCBs are plug-n-play, and built around ST’s STspin ICs, that include control features, a protected output stage and safety functions including non-dissipative over-current protection.
“The motor drivers are ready to use without any hardware configuration,” said ST. “ST has actively supported creation of MikroSDK libraries and code examples, working with MikroElektronika, to deliver software that lets users get the best from each board.”
- STSPIN220 stepper driver Click board with STSPIN220 chip
10V 1.3A, two on-chip 0.4Ω H-bridges, PWM current control, 256-microstep resolution, 3mm x 3mm QFN, 10nA typical stand-by.
- STSPIN820 stepper driver Click board with STSPIN820 chip

- STSPIN250 DC brush motor driver Click board with STSPIN250 chip
1.8 – 10V 2.6A, 0.2Ω H-bridges, 3mm x 3mm, 10nA typical stand-by.
- STSPIN233 dc brushless (BLDC) motor driver Click board with STSPIN233 chip (delivery Q4)
1.8V-10V, three half-bridges with independent input and enable pins, three-shunt sensing, 3mm x 3mm QFN, 10nA typical stand-by.
“With their low motor-voltage capabilities, energy-efficient low-resistance mosfets, low stand-by current, and tiny outline, STspin drivers ensure longer battery life and save space in portable, mobile, and other battery-powered applications, such as smartphone pop-up cameras, gimbals, healthcare products, small appliances, toys, point-of-sale terminals, robots, drones, e-locks, and valves,” claimed the firm.
