詳細說明
Revolutionize your automotive lighting system with the L99LDLH32, a sophisticated 32-channel linear current regulator specially designed for O/LED rear lighting applications. Featuring a high side output configuration, this device is perfectly suited for driving OLED panels with a common cathode. Boasting up to 35 V output driving capability and 32 regulated current sources that can deliver individual currents from 1 mA to 15 mA, the L99LDLH32 offers precise control over each pixel of the OLED panel. With an automotive CAN FD Light compatible communication interface enabling high-speed data transmission of up to 1 Mbit/s, seamless communication with the Commander ECU is ensured. The device's integration of a protocol handler further streamlines the communication process, making it a sophisticated yet user-friendly solution for automotive lighting applications
