STSPIN830

Overview

The STSPIN830 is a compact, versatile three-phase BLDC motor driver designed for Field Oriented Control (FOC) applications. It integrates control logic and a fully protected triple half-bridge power stage in a 24-TQFPN (4x4 mm) package. The device supports an operating voltage range of 7 V to 45 V with a maximum output current of 1.5 A rms. It features a typical RDSon of 1 Ω for the high-side and low-side MOSFETs combined. The STSPIN830 accommodates both single and three-shunt current sensing architectures, enabling flexible driving via six inputs or three PWM signals. It includes non-dissipative overcurrent protection, thermal shutdown, short-circuit protection, undervoltage lockout, and interlocking functions.

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape-and-reel or cut tape, as these do not alter the functional characteristics. Confirm the component status is active before finalizing design-in decisions. Ensure that the selected package variant matches the PCB footprint requirements for the 24-TQFPN form factor. Cross-reference the manufacturer datasheet for any recent product change notices regarding manufacturing sources or assembly processes.

Selection Notes

Select this component when a small footprint is required for three-phase motor drives supporting FOC algorithms. It is suitable for designs needing flexible input configurations between direct PWM and individual switch control. Consider its integrated protection suite for applications requiring reliable operation under fault conditions without external discrete components. Evaluate the 1.5 A rms current capability against the specific motor load requirements.
