DESCRIPTION

The SA305 is an integrated, fully protected, 3 phase brush-

less DC motor driver IC. Three independent half bridges pro-

vide up to 5A of continuous (10A peak) output current under

microcontroller or DSP control.

Thermal, short circuit, shoot through, and over current protec-

tion 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.
