Low-Drop LED Driver TLE 4240 G Target Data Features * * * * * * * * * * * Output current tolerance 20% 60 mA output current Low drop voltage Suitable for use in automotive electronics Wide operation range: up to 45 V Wide temperature range: - 40 C Tj 150 C Output protected against short circuit Overtemperature protection Reverse polarity proof Very small SMD-Package SCT 595 Status output for open Load Type Ordering Code TLE 4240 G SCT 595 Package SCT-595 (SMD) New type Functional Description The TLE 4240 G is a monolithic integrated low-drop LED Driver in the very small SMD package SCT 595. It is designed to supply LEDs under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity and overtemperature. The output is a constant current source which drives LEDs to 60 mA within an accuracy of 20%.
