The standby current of the chip is less than 80nA. It can enter standby mode under logic control and is suitable for battery extended operation in universal racks for drone cameras, educational robots, toothbrushes, razors, medical syringe pumps or small drives and other devices. Internet of Things (IoT) devices.
Its 1.8V-10V input voltage range provides the same basic power as a single lithium-ion battery. Built-in safety features further simplify system design, including over-current, short-circuit and over-temperature protection, UVLO and interlock.
Development ecosystem including Nucleo expansion board (X-NUCLEO-IHM17M1) and related software tools (X-CUBE-SPN17 for STM32Cube) can be used in STSPIN233 to quickly start evaluation and prototyping, including using the easy-to-use STM32Cube Tool software, middleware and application code sample environment.
With the advent of STSPIN233, ST now offers complete miniature monolithic low-voltage drivers for stepper, brushed or brushless motors in small battery-powered devices.
The complete series including STSPIN220, STSPIN230, STSPIN233, STSPIN240 and STSPIN250 are equipped with a dedicated Nucleo evaluation board and X-CUBE software package, providing flexible options including single power, dual power or high current (2.6 arm) power Brush control, and sensorless or sensorless BLDC control.
