Zusammenfassung:An integrated circuit includes first and second transistors, a switch, and a power-on reset (POR) circuit. The first transistor has a first current electrode, a second current electrode, and a control electrode. The second transistor has a first current electrode coupled to the second current electrode of the first transistor, a second current electrode, and a control electrode. The switch is for coupling the first and second transistors to receive a power supply voltage in response to an asserted bias control signal. The POR circuit has a latch-up detection circuit coupled to receive the power supply voltage and to a control terminal of the switch. The latch-up detection circuit is for detecting a low voltage condition of the power supply voltage, and in response, deasserting the bias control signal to decouple the first and second transistors from the power supply voltage.
