TLD2252-2EP

Overview

The LITIX™ Basic+ TLD2252-2EP is a dual channel high-side driver IC with integrated output stages.

The TLD2252-2EP is designed to control LEDs with a current up to 120 mA. In typical automotive applications the device is capable of driving 3 red LEDs per chain (total 6 LEDs) with a current up to 100 mA and even above, if not limited by the overall system thermal properties. Practically, the output current is controlled by an external resistor or reference source, independently from load and supply voltage changes.

Summary of Features

Dual channel device with integrated and protected output stage (current source), optimized to drive LEDs as additional low cost current source
Optimized for low cost combined “stop”/ “tail” function in Rear Combination Light (RCL)
Asymmetric output stages to enhance luminosity control for different functions
High output current (up to 120 mA)
Very low current consumption in sleep mode
Very low output leakage when channel is “off”
Low current consumption during fault
Independent output currents’ control via low power resistors
Additional output current demand supported by LITIX^TM Companion direct drive
PWM engine supports digital dimming with very high accuracy
Intelligent fault management: up to 16 devices can share a common error network with only one external resistor
Reverse polarity protection allows reduction of external components and improves system performance at low battery/input voltages
Overload protection
Wide temperature range: -40°C < TJ < 150°C
Output current control via external low power resistor
Green product (RoHS compliant)
