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

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.
