Product Overview

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

Applications

LED Lighting, Industrial, Computers & Computer Peripherals

Warnings

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.
