NXQ1TXL5 Datasheet | NXP Semiconductors

Low-cost one-chip 5 V Qi pliant 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-pliant 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-pliant receiver is placed, the NXQ1TXL5 starts to municate 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 pensate for power-limited supplies. This low-cost version of the fully integrated NXP Qi-pliant 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.
