Stop Lamp Switch Driver IC
- Project name
- - Stop Lamp Switch Driver IC
- Project objective
- - Replacing mechanical switch by electrical FET
- Project Contents & Scope
- - 과제의 필요성
- - A mechanical switch for stop lamp has some problems like reliability and durability. So electrical switch is replacing mechanical switch.
- - 과제의 필요성
- Main contents
- - On/Off signal output to drive FET according to brake pedal position
- - Integrated charge pump for external H/S switch
- - Integrated switches for low power mode instead of external FET
- - Reverse battery, Ground open/short, Current limit, and over voltage protection
- - -40 degree to 125 degree automotive temperature range.
- 단계별 목표 및 최종목표
- Technical Breakthrough
- - Sensor detect the gap between brake pedal and sensor. Detecting is established by the coil. The input signal from coil is nonlinear. So we should convert this signal to linear signal proportional to the distance by signal processing.
