Infineon Technologies TLD2252-2EP LITIX™ Basic+ High-Side Driver IC

Infineon Technologies TLD2252-2EP LITIX™ Basic+ High-Side Driver IC features integrated output stages and is designed to control LEDs with a current of up to 120mA. In typical automotive applications, the module can drive three red LEDs per chain (six LEDs total) with a current up to 100mA and higher, if not limited by the overall system thermal properties. The output current is controlled by an external resistor or reference source, independent from the load and supply voltage changes. Infineon Technologies TLD2252-2EP LITIX™ Basic+ High-Side Driver IC comes with a pulse width modulation (PWM) engine that supports digital dimming with high accuracy.

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 120mA)
Low current consumption in sleep mode
Low output leakage when channel is "off"
Low current consumption during fault
Independent output current control via low-power resistors

Additional output current demand supported by LITIX™ Companion direct drive
PWM engine supports digital dimming with 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 -40°C to +150°C temperature range
Output current control via external low-power resistor
Green product (RoHS compliant)

Applications

Cost-effective "stop"/"tail" function implementation with shared and separated LEDs per function
Turn indicators
Position, fog, rear lights, and side markers
Daytime running lights

LED indicators for industrial and instrumentation
Animated light functions - wiping indicators and "welcome/goodbye" functions
Interior lighting functions - ambient lighting (including RGB color control), illumination, and dashboard lighting
