DESCRIPTION

The SA303 is a fully integrated switching amplifier

designed primarily to drive three-phase Brushless

DC (BLDC) motors. Three independent half bridges

provide over 10 amperes peak output current under

microcontroller or DSC control. Thermal and short cir-

cuit monitoring is provided, which generates fault sig-

nals for the microcontroller to take appropriate action.

A block diagram is provided in Figure 1.

Additionally, cycle-by-cycle current limit offers user

programmable hardware protection independent of the

microcontroller. Output current is measured using an

innovative low loss technique. The SA303 is built using

a multi-technology process allowing CMOS logic con-

trol and complementary DMOS output power devices

on the same IC. Use of P-channel high side FETs en-

ables 60V operation without bootstrap or charge pump

circuitry.

The Power Quad surface mount package balances ex-

cellent thermal performance with the advantages of a

low profile surface mount package.
