Abstract: In examples, an integrated circuit package comprises a pin exposed externally to the package; at least one resistor coupled to the pin at a first end of the resistor; a first transistor coupled to the at least one resistor at a second end of the resistor and coupled to a voltage source; a second transistor coupled to the at least one resistor at the second end of the resistor and coupled to a ground connection, the at least one resistor and the first and second transistors couple at a first node, the first and second transistors are of different types; and multiple comparators, each of the multiple comparators coupled to a voltage divider network and to the pin.
