STMicroelectronics Low-Voltage STSPIN Motor Drivers

STSPIN ICs use an adaptive current decay control scheme and innovative voltage mode driving for enhanced torque control accuracy that results in motion smoothness. Built-in protection and diagnostic schemes help attain long term reliability for harsh factory automation environments. The STSPIN lineup are available in a wide selection of packages that addresses a wide selection of motor and motion control system design requirements.

The STSPIN820 Stepper Motor Driver integrates control logic and a low R_DSON power stage and is housed in a small QFN 4.0mm x 4.0mm package. The integrated controller implements a PWM current control with fixed OFF time and a microstepping resolution up to 1/256th of the step. The device can be forced into a low consumption state and offers protection features like overcurrent, overtemperature and short-circuit protection.

The STSPIN32F0 Advanced BLDC Controller with embedded STM32 MCU is housed in a 7.0mm x 7.0mm x 1.0mm VFQFPN-48 package. The STSPIN32F0 embeds a triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability of 600mA (sink and source). The high- and low-side switches of the same half-bridge can't be simultaneously driven high thanks to an integrated interlocking function.

The STSPIN32F0A is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes. The STSPIN32F0A features overtemperature, undervoltage lockout protections, and can be put in standby mode to reduce power consumption. The device provides 16 general-purpose I/O ports (GPIO) with a 5V tolerant capability. The STSPIN32F0A also has one 12-bit analog-to-digital converter with up to 9 channels performing conversions in a single-shot or scan modes.

The STSPIN220 is a stepper motor driver that integrates control logic and a low R_DS(on) power stage. The integrated controller implements PWM current control with fixed OFF time and a microstepping resolution up to 1/256th of a step.

The STSPIN233 device integrates a triple halfbridge low R_DS(ON) power stage in a small VFQFPN 3.0mm x 3.0mm x 1.0mm package ideal for small and space constrained applications.

The STSPIN230 device integrates a triple halfbridge low R_DS(ON) power stage in a small QFN 3.0mm x 3.0mm package. The device is designed to operate in battery powered scenarios and can be forced into a zero consumption state, allowing a significant increase in battery life.

The STSPIN240 is a dual brush DC motor driver integrating a low R_DS(ON) power stage in a small QFN 3.0mm x 3.0mm package. Both the full-bridges implement an independent PWM current controller with fixed OFF time.

The STSPIN250 is a single-brush DC motor driver integrating a low R_DS(ON) power stage in a small VFQFPN 3.0mm x 3.0mm  package. The full-bridge implements a PWM current controller with fixed OFF time. The device is designed to operate in battery powered scenarios and can be forced in a zero consumption state allowing a significant increase in battery life. The device offers a complete set of protection features including over current, over temperature and short-circuit protection.
