Moreover, it can be put into standby mode under logic control, making it ideal 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 STSPIN233 is easy and uncomplicated. Its input-voltage range of 1.8V-10V allows use with a power source as basic as a single Li-ion cell. Built-in safety features further simplify system design, including over-current, short-circuit, and over-temperature 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.
With the arrival of the STSPIN233, ST now offers a complete portfolio of miniature monolithic low-voltage drivers for stepping, brush, or brushless motors in small battery-powered devices.
The complete family, comprising STSPIN220, STSPIN230, STSPIN233, STSPIN240, and STSPIN250, each with a dedicated Nucleo evaluation board and X-CUBE software package, offers flexible choices including single, dual, or high-current (2.6Arms) brush motor control, and sensed or sensorless BLDC control.
The STSPIN233 is available now as a compact 3mm x 3mm QFN, priced from $0.95 for orders of 1000 pieces.
