Publication number: 20230184817Abstract: A circuit comprises a load transistor and a current measuring circuit that is coupled to the load transistor. The load transistor has a main current path, which is connected between a first supply node and an output pin for connecting a load. The current measuring circuit has a sense transistor coupled to the load transistor. The current measuring circuit is designed to deliver a measuring current that represents a load current flowing through the load transistor. The circuit also comprises an analog-to-digital converter with a current input, and a digital-to-analog converter. The analog-to-digital converter is designed to output a digital signal representing an input current of the analog-to-digital converter. The digital-to-analog converter is designed to output an output current that depends on the digital signal. A control circuit is designed to output the measuring current.Type: ApplicationFiled: November 25, 2022Publication date: June 15, 2023Inventors: Christian Djelassi-Tscheck, Alexander Mayer, Mario Tripolt

Patent number: 11527881Abstract: A circuit includes a monitor circuit. The monitor circuit includes a nonlinear functional unit configured to receive a current sense signal and to generate a power signal representing the power of the current sense signal. The circuit further includes a first filter configured to receive the power signal and to generate a first filtered signal and a second filter configured to receive an input signal that depends on the current sense signal and to generate a second filtered signal.
