Abstract
A high-voltage fail-safe input/output (I/O) interface circuit includes a voltage-divider circuit coupled to an I/O pad of the I/O interface circuit, and a selector circuit configured to couple, to a power supply line of the I/O interface circuit one of an output of the voltage-divider circuit or and I/O supply voltage. The voltage-divider circuit and the selector circuit are implemented on the same chip with the I/O interface circuit.
