Infineon LITIX™ Basic + -extension to the existing LITIX™ Basic family

Infineon LITIX™ Basic+ LED drivers serve as perfect extension to the existing LITIX™ Basic family. LITIX™ Basic+ linear constant current sources with their 1 to 3 inputs/outputs build a scalable family to reduce system costs (e.g. less external components needed, introduction of power shift feature). Output currents from 5 mA up to 360 mA (with power shift) can be served with LITIX™ Basic+. The family also has optimized diagnosis features as well as an improved output current accuracy. Several selectable fault management modes offer high design-in flexibility.

Key features

• Programmable OL/SC fault management
• Current range from 5mA to 360 mA at high current accuracy (5%)
• Flexible Single LED short diagnosis for latched and retry strategies
• High accuracy PWM via integrated PWM engine

Additional features

• LITIX™ Basic+ as high-current LCS with overload protection
• External component need reduced
  Direct PWM connection
  Shared ERRN network
  Shared DEN/EN network
  Shared D/DS pin capacitor
  Direct OUTSET and INSET connection
• Low active error network
• SLS diagnosis with tunable threshold
• Improved and precise diagnosis
• Design flexibility by footprint compatibility
• Single LED operation possible

Applications

• Turn indicators
• Position, fog, rear lights and side markers
• Animated light functions like wiping indicators
• Day Running Light
• Interior lighting functions like ambient lighting
• LED indicators (industrial and instrumentation)
