MSA303 is a fully integrated three-phase driver designed primarily to drive Brush-Less DC (BLDC), Permanent Magnet Synchronous (PMSM) motors or DC/AC converters. The module uses Silicon Carbide MOSFET technology to improve efficiency over other devices in its class. Three fully independent half-bridges provide 40 A of continuous current. MSA303 is built on a thermally conductive, but electrically isolated substrate to provide the most versatility and ease in heatsinking.
Protection features include under-voltage lockout (UVLO) function and active Miller clamping to improve reliability. Also included in the module are Silicon Carbide Schottky Barrier free-wheeling diodes in parallel to the body diode of each MOSFET. No external output protection diodes are required.
By integrating three half-bridges, gate drive circuitry, and protection features into a single module, the MSA303 supports system designs where size, weight, and power (SWaP) are critical considerations. Its compact architecture enables high power delivery within a small footprint, helping engineers optimize space in demanding application environments.
