STA508 Datasheet 40 V, 4.5 A quad power half bridge Features Multipower BCD technology Minimum input output pulse width distortion 200 m R complementary DMOS output stage dsON CMOS compatible logic input Thermal protection PowerSO-36 Thermal warning output with exposed pad up Undervoltage protection Description STA508 is a monolithic quad half bridge stage in Multipower BCD technology. The device can be used as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and as half bridge (Binary mode) with half current capability. The device is particularly designed to make the output stage of a stereo all-digital high efficiency (DDX) amplifier capable to deliver 80 + 80 W THD = 10 % at V CC = 35 V output power on 8 load. In single BTL configuration is also capable to deliver a peak of 160 W THD = 10 % at V = 35 V on 4 load. The input pins have threshold proportional to V pin CC L voltage.
