SA305 Overview

PULSE WIDTH MODULATION AMPLIFIER

SA305
M I C R O T E C H N O L O G Y
FEATURES
• LOW COST 3 PHASE INTELLIGENT SWITCHING
AMPLIFIER
• 3 FULLY PROTECTED HALF BRIDGES
• UP TO 60V SUPPLY
• OUTPUT CURRENT - 5 AMPS (CONT) PER HALF BRIDGE
• NO “SHOOT THROUGH” CURRENT
APPLICATIONS
• 3 PHASE BRUSHLESS DC MOTORS
• 3 INDEPENDENT SOLENOID ACTUATORS
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.
