ИС беспроводного зарядного устройства NXQ1TXH5/101J

Контроллер беспроводного передатчика питания , 3.5В до 5.25В, HVQFN-32

Single chip wireless transmitter for a 5V Qi-certified/compliant low power wireless charger. It offers a fully integrated solution that includes a 5V full-bridge power stage, as defined in WPC 5V Qi standards A5, A11, A12 and A16. The device uses a dedicated analogue ping circuitry to detect devices. The IC is optimized to operate from a 5V USB power supply and uses Smart Power Limiting (SPL) to adjust the output power automatically to compensate for power-limited supplies. The device supports Foreign Object Detection (FOD). Typically used in smartphones, toys, shavers, pads and other handheld devices, smartwatches and other wearables.

• Low EMI radiation meeting EN55022 radiated and conducted emission limits
• Very few external components needed, minimizing cost and board space
• Power stage protected against overcurrents and overtemperature
• Dual channel amplitude shift keying (ASK) demodulation
• Demodulates communication packets from Qi-compliant receivers
• PID regulation for power drive and control
• NTC input for external temperature check and protection
