产品概述
The TL4242-Q1 device is an integrated adjustable constant-current source, driving loads
up to 500 mA. One can adjust the output current level through an external resistor. The device
design is for supplying high-power LEDs (for example, OSRAM Dragon LA W57B) under the severe
conditions of automotive applications, resulting in constant brightness and extended LED lifetime.
The device comes in the DRJ (WSON) and KTT (TO-263) package. Protection circuits prevent damage to
the device in case of overload, short-circuit, reverse polarity, and overheat. The device provides
the connected LEDs protection against reverse polarity as well as excess voltages up to
45 V.The integrated PWM input of the TL4242-Q1 device permits LED brightness regulation by
pulse-width modulation (PWM). The high-input impedance of the PWM input allows operating the LED
driver as a protected high-side switch.
