TLD1124 - Basic LED Driver

Download the TLD1124 datasheet PDF. This datasheet also covers the TLD1124EL variant, as both devices belong to the same basic led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The LITIX™ Basic TLD1124EL is a one channel high side driver IC with integrated output stage.

It is designed to control LEDs with a current up to 360 mA.

In typical automotive applications the device is capable to drive i.e.

Key Features

  • 1 Channel device with integrated output stage (current source), optimized to drive LEDs with output current up to 360 mA.
  • Low current consumption.
  • PWM-operation supported via VS-pin.
  • Output current adjustable via external low power resistor and possibility to connect PTC resistor for LED protection during over temperature conditions.
  • Reverse polarity protection and overload protection.
  • Undervoltage detection.
  • Open load and short cir.
