    Abstract: An integrated circuit (IC) (200) with negative potential protection includes a switch (M1), a gate drive circuit (GD) and a comparator (CMP1). The switch (M1) includes a double-diffused metal-oxide semiconductor (DMOS) cell formed in a first-type epitaxial pocket (108), which is formed in a second-type substrate (110). The switch (M1) also includes a second-type+ isolation ring (110A) formed in the substrate (110) to isolate the first-type epitaxial pocket (108). An output of the gate drive circuit (GD) is coupled across a gate and a source of the switch (M1). An output of the comparator (CMP1) is coupled to a second input of the gate drive circuit (GD) and a first input of the comparator (CMP1) receives a reference signal. A second input of the comparator (CMP1) is coupled to the epitaxial pocket (108). The comparator (CMP1) provides a turn-on signal that causes the switch (M1) to conduct current, when a signal at the second input of the comparator (CMP1) is below the reference signal.

    Abstract: A liquid metal rotary connector (16) for a vehicle steering mechanism (10) utilizes a conductive alloy comprising Gallium, Indium, Tin and Zinc to electrically couple stationary and rotary terminals (26a, 26b; 28a, 28b) of the connector (16). The alloy is a liquid at ambient temperatures, and has a melting point of -36°C, though testing has shown that it operates satisfactorily at temperatures as low as -40°C. In a preferred arrangement, the rotary connector (16) provides a two-wire connection through which power is supplied from the steering column (12) to the steering wheel (14), and electronic modules (22, 24) located in the steering column (12) and the steering wheel (14) support bi-directional data communication through voltage and current modulation of the supplied power.
