L99LDLH32TR

L99LDLH32TR is a 32 channels LED driver with automotive CAN FD light interface. The monolithic 32-channel linear current regulator specifically designed for automotive exterior O/LED rear lighting applications. Thanks to the high side configuration of the output channels, it is suitable to drive OLED panel with common cathode. It guarantees up to 35V output driving capability to cover the OLED forward voltage wide spread and features 32 regulated current sources able to provide from 1mA up to 15mA individually programmable current to drive each pixel of the OLED panel independently. As the other device in the family, it integrates a robust purely automotive CAN FD Light compatible communication interface which allows a high rate data transmission and uses CAN FD structure for long frames. Application includes automotive OLED rear lighting, automotive ambient lighting.
