Overview

STA518 40V 3.5A quad power half bridge Feature ■ ■ ■ ■ ■ ■ ■ ■ Multipower BCD technology Minimum input output pulse width distortion 200mΩ RdsON complementary dmos output stage CMOS compatible logic inputs Thermal protection Thermal warning output Under voltage protection Short circuit protection The device is particularly designed to make the output stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver an output power of 24W x 4 channels @ THD = 10% at Vcc 30V on 4W load in single ended configuration.

It can also deliver 50 + 50W @ THD = 10% at Vcc 29V as output power on 8W load in BTL configuration and 70W @ THD = 10% at Vcc 34V on 8W in single paralleled BTL configuration.

The input pins have threshold proportional to VL pin voltage.
