Abstract
A power supply integrated circuit is provided which makes it possible to make an on-vehicle apparatus compact and to allow power supply cable communication having resistance to noise. The power supply integrated circuit is connected to a micro-controller incorporated in an ECU and a power supply cable. The power supply integrated circuit has an LPF and a regulator. The power supply integrated circuit also has an interface circuit, a BPF, a transmitting section, and a receiving section. The LPF passes only the power supply voltage, and the BPF passes only transmission signal.
