STMicroelectronics STSPIN233 low-voltage motor driver

Click2Contact

STMicroelectronics’ STSPIN233 low-voltage motor driver is suitable for both single- and three-shunt brushless motor driving, integrating a 200 mΩ 1.3 A_rms power stage in a slim and compact 3 x 3 mm package.

The device has low standby current at less than 80 nA. Moreover, it can be put into standby mode under logic control, making it suitable for extending operation from batteries in equipment like drone-camera gimbals, educational robots, toothbrushes, shavers, medical syringe pumps or small drives in IoT devices.

Powering the product is easy and uncomplicated. Its input-voltage range of 1.8–10 V allows use with a power source as basic as a single Li-ion cell. Built-in safety features further simplify system design, including overcurrent, short-circuit and overtemperature protection, UVLO and interlocking.

A development ecosystem comprising a Nucleo expansion board (X-NUCLEO-IHM17M1) and related software tools (X-CUBE-SPN17 for STM32Cube) is available for the STSPIN233, to jump-start evaluation and prototyping leveraging the easy-to-use STM32Cube software environment that includes tools, middleware and application-code examples.
