TL4242-Q1 描述
The TL4242 is an integrated adjustable constant-current source, driving loads up to 500 mA. The output current level can be adjusted via an external resistor. The device is designed to supply high-power LEDs (for example, OSRAM Dragon LA W57B) under the severe conditions of automotive applications, resulting in constant brightness and extended LED lifetime. It is provided in the DRJ (QFN) package. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity, and overheat. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45 V.
The integrated PWM input of the TL4242 permits LED brightness regulation by pulse-width modulation (PWM).
