A low-voltage motor driver suitable - STSPIN233
Post Date: 2018-05-03
ST's SSTPIN233 is a low-voltage motor driver for single-shunt and three-shunt brushless motor drives and integrates a 200mΩ 1.3Arms power stage in a 3mm x 3mm package.
The chip's standby current is less than 80nA. It can enter standby mode under logic control and is suitable for battery expansion operations in drone camera universal racks, 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 allows the same basic power supply as a single Li-Ion battery. Built-in safety features further simplify system design including overcurrent, short circuit and overtemperature protection, UVLO and interlocking.
The development ecosystem including the Nucleo expansion board (X-NUCLEO-IHM17M1) and related software tools (X-CUBE-SPN17 for STM32Cube) can be used in the STSPIN233 to quickly start evaluation and prototyping including tools using the easy-to-use STM32Cube software, Middleware and application code sample environment.
With the advent of the STSPIN233, ST now offers a complete miniature monolithic low-voltage driver for stepper, brush or brushless motors in small battery-powered devices.
The complete series including the STSPIN220, STSPIN230, STSPIN233, STSPIN240 and STSPIN250 are equipped with dedicated Nucleo Evaluation Boards and X-CUBE software packages, offering flexible options, including single-supply, dual-supply or high-current (2.6 Arms) brushes Control, and sensorless or sensorless BLDC control.
