TDA7473 Overview
This device is a quad power driver circuit in BTL configuration, intended for use as a power driver for servo systems with a single supply. It’s specially dedicated to pact disc players SO28 (24+2+2) and it’s capable of driving focus & tracking actuators sledge & spindle motors. The regulators are mainly used to have a 5V supply for the power part and a lower programmable voltage for the logic circuits.
