Smart Headlamp Unit
Today’s Smart Headlamp Systems require high reliability electronic components to ensure safe and proper operation under all conditions. Most modern systems drive a large variety of lamps (incandescent, HID, Xenon) with advanced diagnostics (bulb outage detection, overload, etc) and drive features (PWM, DC). More advanced systems offer headlamp levelling and bend lighting control. From bridge, high/low side drivers and advanced regulators to low cost, high performance microcontrollers, coupled with an extensive standard product offering, ST has a broad range of solutions to choose from. A sampling of ST products that are applicable to Smart Headlamp Systems can be found in the following block diagram.
