... SHORT CIRCUIT PROTECTION ■ 2 DESCRIPTION STA506 is a monolithic quad half bridge stage in Mul- tipower BCD Technology. The device can be used as dual bridge or reconfig- ured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and as half bridge (Binary mode) with half current capability. ...

... Figure 8. STA506 Block Diagram Binary Half-Bridge Mode TRI-STATE 3.1 Logic Interface and Decode: The STA506 power outputs are controlled using one or two logic level timing signals. In order to provide a proper logic interface, the Vbias input must operate at the dame voltage as the DDX control logic supply. 3.2 Protection Circuitry: The STA506 includes protection circuitry for over-current and thermal overload conditions ...

... L 3.4 Parallel Output / High Current Operation: When using DDX Mode output , the STA506 outputs can be connected in parallel in order to increase the output current capability to a load. In this configuration the STA506 can provide 80W into 8 ohm 120W into 4ohm. This mode of operation is enabled with the CONFIG pin (pin.24) connected to VREG1 and the inputs combined INLA=INLB, INRA=INRB and the outputs combined OUTLA=OTLB, OUTRA=OUTRB ...
