TLD2311ELXUMA1

TLD2311ELXUMA1 is a LITIX™ basic three-channel high-side driver IC with integrated output stages. It is designed to control LEDs with a current of up to 120mA. In typical automotive applications, the device is capable of driving i.e. 3 red LEDs per chain (total 9 LEDs) with a current up to 60mA, which is limited by thermal cooling aspects. The output current is controlled practically independently of load and supply voltage changes. The application includes exterior LED lighting applications such as tail/brake light, turn indicator, position light, side marker, interior LED lighting applications such as ambient lighting (e.g. RGB), interior illumination and dashboard lighting.
