New Click boards feature STSPIN motor drivers

Using the modules, STSPIN drivers can be used with MikroElektronika prototyping boards and other systems with a mikroBUS socket.

ST’s STSPIN ICs integrate advanced control features, a protected output stage, and safety functions in a small footprint. The devices are situated on the new plug-and-play Click boards and ready to use without hardware configuration. ST has also worked with MikroElektronika to create MikroSDK libraries and code examples.

The STSPIN220 Click board uses the STSPIN220 IC, a 10V stepper driver with the 256-microstep resolution in a 3mm x 3mm QFN package. It offers a low 10nA (typical) standby current and delivers up to 1.3A to drive the motor with PWM current control through each of the two on-chip 0.4Ω H-bridges.

The STSPIN820 Click board features the STSPIN820 stepper driver and is intended to balance cost and performance for 7V-45V applications. It has a 256-microstep resolution and delivers up to 1.5A in a 4mm x 4mm QFN.

The STSPIN250 Click board is built around the 3mm x 3mm STSPIN250, which ST claims is the smallest high-current DC brush motor driver on the market. The device is intended for motor voltages from 1.8V to 10V and it is capable of supplying up to 2.6A through 0.2Ω on-resistance H-bridges. The chip also has an extremely low 10nA (typical) standby current.

The final board of the four is the STSPIN233 Click board, which has been designed for brushless DC (BLDC) motor drives. The 3mm x 3mm STSPIN233 IC has three half-bridges with independent input and enable pins and supports 3-shunt sensing. For 1.8V-10V motor operation, the STSPIN233 has 10nA (typical) standby current.
