The SA306 is a low cost three phase intelligent switching amplifier directly connects to most embedded Micro-controllers and Digital Signal Controllers. Integrated gate driver logic with dead-time generation and shoot-through prevention.
The SA306 3‑Phase Switching Amplifier is a fully integrated driver intended for three‑phase brushless DC motors and other high‑current loads. It features independent half‑bridge outputs, integrated gate‑driver logic with dead‑time, and programmable cycle‑by‑cycle current limiting.
The device operates from 8.5 V to 60 V, delivers over 15 A peak per phase (5 A continuous per phase), and includes thermal and over‑current protection. Pin descriptions, timing diagrams, and thermal management guidelines are provided for designers.

The SA306 can deliver over 15 A peak output current per phase.
It operates from 8.5 V up to 60 V.
A thermal warning is generated when the die reaches approximately 135 °C.
The amplifier is designed primarily to drive three‑phase brushless DC motors.
