The SA305 is an integrated, fully protected, 3 phase brushless DC motor driver IC. Three independent half bridges provide up to 5A of continuous (10A peak) output current under microcontroller or DSP control.
Thermal, short circuit, shoot through, and over current protection are included in this power device. Fault status indication and current level monitors are provided directly to the controller. The SA305 is built using a multi-technology process allowing CMOS logic control and DMOS output power devices on the same IC. Output current is measured using an innovative low loss technique. The SIP package offers superior thermal performance with a flexible footprint.
