The switches can be operated as push-pull, highside or low-side switches using inputs QCFG1 and QCFG2 (open, high and low) and are enabled or disabled via input OEN. They are designed to cope with high driver currents of 100 m A (RSET = 8.2 kΩ), are current limited and also short-circuit-proof in that they shut down should excessive temperature or an overload occur. The output current limit can be set via an external resistor at ISET. The protective overload feature is included here as an integrator so that capacitive loads...
