Abstract
A semiconductor device includes a resistor terminal, a reference voltage generator and a detector. The resistor terminal is connected to an external resistor. The reference voltage generator generates at least one reference voltage. The detector generates a detection signal based at least in part on a resistor terminal voltage and the at least one reference voltage. The detection signal indicates a state of an electrical connection to the resistor terminal. The resistor terminal voltage is a voltage at the resistor terminal.
