 SA310 Data Sheet

The SA310 is a fully integrated three-phase driver designed primarily to drive Brushless DC (BLDC) and 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 independent half-bridges provide up to 80A peak output current under direct microcontroller or DSC control. SA310 is built on a thermally conductive, but electrically isolated substrate to provide the most versatility and ease in heatsinking.

The amplifier protection features include Under-voltage lockout (UVLO) function and active Miller clamping to reduce switching noise and improve reliability. Also included in the module are Silicon Carbide Schottky Barrier free-wheeling diodes to protect the body diode of each MOSFET. No external output protection diodes are required. The SA310's integrated gate drivers provide transformer isolation between the inputs and high-voltage outputs.
