DESCRIPTION
The SA305 is an integrated, fully protected, 3 phase brush-
less DC motor driver IC. Three independent half bridges pro-
23 Pin SIP
Package Style EX
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
Y _{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
R _{performance with a flexible footprint.}
