ABSTRACT:
An integrated circuit switch made with CMOS processes contains a high voltage, high current field effect output transistor. The output transistor serves as a switch and is connected in series with an external load which is to be controlled by the switch. The integrated circuit also contains over current protection circuits and over temperature protection circuits. A circuit also provides fault indications which can be used to determine whether the over current or the over temperature limits were exceeded to shut off the switch.
