STMicroelectronics STSPIN830
STSPIN830 - Compact and versatile three-phase and three-sense BLDC motor driver
STSPIN830 is a compact and versatile field oriented control FOC ready three-phase motor driver. It integrates in a very small 4 x 4 mm QFN package, both the control logic and a fully protected low RDSon triple half-bridge power stage.Thanks to a dedicated MODE input pin the device offers the freedom to decide whether to drive it through 6 inputs (one for each power switch) or a more common 3 PWM direct driving inputs.
The STSPIN830 supports both single and three shunts architectures and embeds a PWM current limiter based on user settable values of reference voltage and OFF time.The devices can be forced in a low consumption state reducing the total current consumption down to less than 45 μA.
As with all other devices from the STSPIN family, the STSPIN830 integrates a complete set of protections for the power stages (non-dissipative overcurrent, thermal shutdown, short-circuit, undervoltage lockout and interlocking) making it a bulletproof solution for the new wave of demanding industrial applications.
