<P>PROBLEM TO BE SOLVED: To provide a discharge path circuit for use in a power supply unit of a driver IC that can control the movement of a head lamp precisely. <P>SOLUTION: A discharge path circuit is a circuit providing a discharge path of an input stage for an integrated circuit IC including a power input port connected to a first input and an operation mode selection port connected to a second input. The discharge path circuit includes an LC filter interconnected between the power input port and the first input to filter noise on a power source, and a resistance element interconnected between the first input and a ground terminal. The resistance element provides a discharge path for discharging a voltage charged by the LC filter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
