Description
The Basic LED Driver TLD1125EL is a one channel high side driver IC with integrated output stage. It is designed
to control LEDs with a current up to 360 mA. In typical automotive applications the device is capable to drive i.e.
3 red LEDs with a current up to 180 mA, which is limited by thermal cooling aspects. The output current is
controlled practically independent of load and supply voltage changes.
