The STSPIN948TR from STMicroelectronics is a Dual Full Bridge Driver that is ideal for stage lighting, factory automation, ATM and money handling machines, textile machines, home appliances, robotics, antenna control, and vending machine applications. This motor driver requires an input voltage of 2.8 - 3.6 V. It is designed for brushed DC motors and bipolar stepper motors, delivering an output current of 4.5 A for reliable motor control. This motor driver benefits from high dynamic performance and the ability to achieve high-frequency PWM control. It offers an independent full-bridge configuration with a current limiter, allowing adjustable threshold and OFF-time, along with the flexibility to choose between slow or mixed decay for superior motor control.
This motor driver includes two amplifiers with a fixed amplification factor for current sensing, utilizing an external shunt resistor to ensure accurate monitoring of motor current levels. It offers multiple ways of operation, providing a high level of flexibility to meet diverse motor control requirements. This motor driver ensures the longevity of the system with a complete set of protection features, including over-current, over-temperature, and low bus voltage detection, safeguarding the motor and the driver from potential damage. It is available in a surface-mount package that measures 7 x 7 x 1 mm.
