Overview
The STSPIN830 is a compact and versatile field-oriented control (FOC) ready three-phase motor driver produced by STMicroelectronics. It integrates both the control logic and a fully protected low RDSon triple half-bridge power stage within a small 4 x 4 mm QFN package. This device offers flexibility in driving methodology, allowing users to choose between 6 inputs (one for each power switch) or 3 PWM direct driving inputs through a dedicated MODE input pin. The STSPIN830 supports both single and three shunts architectures and includes a PWM current limiter based on user-settable values of reference voltage and OFF time. It also features a low consumption state, reducing total current consumption to less than 45 μA, and includes a comprehensive set of protections for the power stages, making it a robust solution for demanding industrial applications.
