STMicroelectronics announces STSPIN9 series of high-current motor driver chips

     STMicroelectronics, a leading global semiconductor manufacturer, recently announced the release of their new STSPIN9 series of high-current motor driver chips. This range of products is designed to provide reliable drive solutions for high-performance motors in a variety of application scenarios.

     The STSPIN9 series chip is an integrated circuit capable of controlling and driving high-current motors. They are highly integrated and enable multiple functions such as speed control, position control and torque control in motor control systems. These chips use advanced IRF5210STRLPBF technology to provide efficient motor drive performance with low power consumption and high reliability.

     The STSPIN948 chip has two full-bridge topologies that can be configured into different drive modes, giving developers the flexibility to select different configurations and drive multiple motors with different power ratings. The STSPIN948 has several PWM current control modes to choose from, including fixed shutdown time or current threshold Settings, and supports five operating modes. The 4.5AIC comes in a 7mm x 7mm VQFPN48 package.

     The STSPIN958 has only one full-bridge topology and can be configured to drive two unidirectional motors, a bidirectional DC brush motor, or a higher current unidirectional motor if the power output pins are connected in parallel. The chip also offers a fixed turn-off time and configurable current control mode options, as well as dual half bridge, single full bridge and half bridge parallel configurations, supporting seven motor drive modes. The 5.0A STSPIN958 comes in a 5mm x 5mm VFQFPN32 package.

     The flexible configuration of the STSPIN948 and STSPIN958 motor drives makes them suitable for a wide variety of industrial applications, including factory automation systems, textile machines, industrial robots, home robots, stage lighting systems, ATMs and money counters, antenna controllers, vending machines, and most commonly used appliances and industrial equipment.

     Both driver chips allow designers to use an external resistor to set the output transistor's voltage swing rate to 0.3V/ns, 0.6V/ns, 1.2V/ns, or 2V/ns to find an ideal balance between power consumption and electromagnetic compatibility. Built-in dead time mechanism can effectively prevent breakdown, the on-resistance of each MOSFET is only 200m. Can maximize energy efficiency. The 280ns propagation delay ensures a fast response to system commands.

     The STSPIN9 series chips can be used in a variety of motor types, including brushless DC motors (BLDC), brushless DC motors (DC), stepper motors, and other high-current motors. This makes them ideal for applications in areas such as automotive, industrial automation, home appliances and consumer electronics.

     These chips have a wide input voltage range, ranging from 8V to 95V. This means that they can be adapted to a variety of different power systems and can work well in environments with high voltage fluctuations. In addition, the STSPIN9 series chips are available in a variety of different power levels and package options to meet the needs of different applications.

     STSPIN9 series chips also have a wealth of protection functions, including overheat protection, undervoltage protection, overcurrent protection and short circuit protection. These protection functions can effectively protect the motor and chip from damage, and improve the reliability and stability of the entire system.

     In addition, the STSPIN9 series chips also provide a wealth of interface options to facilitate communication and control with other external devices. These interfaces include PWM input, analog input, SPI bus and I2C bus. This allows the chip to be integrated with a variety of different controllers and sensors, and to implement a variety of different control algorithms.

     In general, the STSPIN9 series of high-current motor driver chips released by ST have the characteristics of high integration, high efficiency, low power consumption, high reliability and rich protection functions, which are suitable for a variety of application scenarios of high-current motor drivers. This line of chips will help system designers achieve greater energy efficiency and reliability, and provide a better user experience.
