NXQ1TXL5 Overview
Description
The NXQ1TXL5 is a controller and driver IC for a low-cost 5 V Qi-compliant low-power wireless charger. It offers a fully integrated solution that includes a 5 V full-bridge power stage, as defined in Wireless Power Consortium (WPC) 5 V Qi standards A5, A11, A12 and A16.
Key Features
- Single-chip WPC 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 by integrating an analog ping circuit; standby (wait state) power 10 mW (typical)
- Power stage protected against overcurrents and overtemperature
- Dual-channel ASK demodulation
- Demodulates communication packets from Qi-compliant receivers
- PID regulation for power drive and control
- Internal 1.8 V
