The L99LDLH32 is a 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, the L99LDLH32 is suitable to drive OLED panel with common cathode. It guarantees up to 35 V output driving capability - to cover the OLED forward voltage wide spread - and features 32 regulated current sources able to provide from 1 mA up to 15 mA individually programmable current to drive each pixel of the OLED panel independently. As the other device in the family (L99LDLL16), the L99LDLH32 integrates a robust purely automotive CAN FD Light compatible communication interface which allows a high rate data transmission (up to 1 Mbit/s) and uses CAN FD structure for long frames. Besides the CAN FD Light compatible physical layer, the device also integrates the protocol handler, so no additional external devices are needed to facilitate communication with Commander ECU. The L99LDLH32 can operate in bus mode using CAN FD Light compatible interface or in stand-alone/fail-safe mode using internal Few Time Programmable (FTP) memory registers.
