Čip NXQ1TXA5 je určený pre riadenie bezdrôtových nabjacích staníc malých výkonov správajúci sa podľa Qi štandardu A5, A11, A12 a A16 (Wireless Power Consortium - WPC).

Vlastnosti

• One-chip WPC 1.1.2 Qi-compliant device for A5/A11/A12/A16 5 V single-coil low- power transmitter
  
• Operates from 5 V supply
  
• Integrated high-efficiency full- bridge power stage with low EMI radiation meeting EN55022 radiated and conducted emission limits
  
• Very few external components required, minimizing cost and board space
  
• Extremely low- power receiver detection circuitry; standby power 10 mW (typical)
  
• Power stage fully protected against overcurrents and overtemperature
  
• Fully integrated accurate coil current measurement
  
• Demodulates and decodes communication packages from Qi-compliant receivers
  
• PID regulation for closed-loop power drive and control
  
• Internal 1.8 V digital supply generation
  
• LED (x2) and buzzer outputs
  
• NTC input for external temperature check and protection
  
• On-chip thermal protection
  
• Small HVQFN 32-pin package (5 x 5 mm) with 0.5 mm pitch
  
• FOD with automatic switching between V1.1 and V1.0 for legacy receiver support
  
• FOD levels can be adjusted using external resistors to compensate for application differences to meet Qi certification requirements
  
• Smart Power Limiting (SPL) function to adapt to power-limited 5 V supplies
  
• Static Power Reduction (SPR) function to limit power consumption
  
• Supports Near Field Communication (NFC) TAG applications with delayed start-up
