TLD2252-2EP
概要
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.
特長
- 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 LITIXTM 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)
推奨アプリケーション例
- Cost effective “stop”/ “tail” function implementation with shared and separated LEDs per function
- Turn indicators
- Position, fog, rear lights and side markers
- Animated light functions like wiping indicators and “welcome/goodbye” functions
- Day Running Light
- Interior lighting functions like ambient lighting (including RGB color control), illumination and dash board lighting
- LED indicators for industrial applications and instrumentation
