TL4242 Datasheet PDF

●The TL4242DRJR is an adjustable LED Driver designed to supply high-power LEDs. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity and over-temperature. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45V. The integrated PWM input of the TL4242 permits LED brightness regulation by pulse-width modulation (PWM). Due to the high input impedance of the PWM input, the LED driver can be operated as a protected high-side switch.

● PWM brightness regulation

● Low drop voltage

● Open-load detection

● Over-temperature protection

● Short-circuit proof

● Reverse-polarity proof

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
