ST悬挂式接线盒解决方案

Junction Box Underhood
Today’s Junction Box Systems require high reliability electronic components to ensure safe and proper operation under all conditions. Most modern systems drive a large variety of loads: from lamps (incandescent, HID, Xenon) with advanced diagnostics (bulb outage detection, overload, etc) and drive features (PWM, DC) to motors substituting existing electromechanical relays. 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 regardless of where the unit is mounted in the vehicle (cabin, rear, underhood). A sampling of ST products that are applicable to Junction Box Systems can be found in the following block diagram.
