Description

  VAS1085Q is a wide input range constant current LED driver to provide cost-effective solution for automotive lighting and other LED illumination application. For normal application, VAS1085Q needs only one external resistor to set the LED current. For high current application, several VAS1085Q can be connected in parallel. 

  VAS1085Q can achieve 85% full setting current with only 1.35V input voltage, with this feature, it is ideal for applications with extremely low power supply voltage. 

  The device integrates over temperature protection, the LED current will automatically reduce when the die temperature reaches 140°C, and shut down when the die temperature reaches 160°C.
