NXQ1TXL5

NXQ1TXL5 Low-cost one-chip 5 V Qi compliant transmitter Rev. 1 — 8 April 2016 Product short data sheet 1. General 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. The NXQ1TXL5 uses a dedicated analog ping circuitry to detect devices. With this analog ping circuitry, an extremely low standby (wait state) power consumption is achieved. When a Qi-compliant receiver is placed, the NXQ1TXL5 starts to communicate with it. After the receiver is recognized, it safely initiates wireless power transfer from the transmitter to the receiver. The device is optimized to operate from a 5 V USB power supply and uses Smart Power Limiting (SPL) to adjust the output power automatically to compensate for power-limited supplies. This low-cost version of the fully integrated NXP Qi-compliant wireless power transmitted does not support Foreign Object Detection (FOD). To indicate the charging status or standby status, the NXQ1TXL5 has two LED outputs for the user interface. The NXQ1TXL5 is available in a 5 mm  5 mm, 32-pin HVQFN package. 2.
