TLD1125ELXUMA1

The TLD1125ELXUMA1 from Infineon is an automotive grade 1 channel high side current source with integrated output stage in 14 pin SSOP package. It is designed to control LEDs with a current up to 360mA. In typical automotive applications the device is capable to drive i.e. 3 red LEDs with a current up to 180mA which is limited by thermal cooling aspects. The output current is controlled practically independent of load and supply voltage changes. Designed for exterior LED lighting applications such as tail/brake light, turn indicator, position light and side marker. The device is also well suited for interior LED lighting applications such as ambient lighting, interior illumination and dash board lighting.
