NXQ1TXH5 One-chip 5 V Qi wireless transmitter Rev. 1.1 — 4 March 2016 Product short data sheet 1. General description The NXQ1TXH5 is a controller and driver IC for a 5 V Qi-certified/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 NXQ1TXH5 uses a dedicated analog ping circuitry to detect devices. With the analog pin circuitry, an extremely low standby (wait state) power consumption is achieved. When a Qi-compliant receiver is placed, the NXQ1TXH5 starts to communicate with it. After the receiver is recognized, it safely initiates wireless power transfer from the transmitter to the receiver, while monitoring for fault conditions such as overheating or interference from metal objects. 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. The device supports Foreign Object Detection (FOD). LED outputs and a buzzer output are available for the user interface. The LED outputs feature a number of blinking modes. Static Power Reduction (SPR) allows multiple NXQ1TXH5-based transmitters to operate from a single USB power supply by limiting power consumption per device. The NXQ1TXH5 is available in a 5 mm  5 mm, 32-pin HVQFN package. 2.

Ideal for charging wearables 3. Applications  Wireless Power Consortium (WPC) Qi certified/compliant wireless power transmitters  Wireless charger for (smart)phones, toys, shavers, pads, and other handheld devices  High-efficiency low-power wireless charger for smartwatches and other wearables 4. Quick reference data Table 1. Quick reference data Symbol Parameter Conditions Min Typ Max Unit VDDP IDDP power supply voltage on pins VDDP1 and VDDP2 3.4 - 5.25 V power supply current on pins VDDP1 and VDDP2 wait state (average current) - 2 - mA power transfer state (no load) - 15 - mA 1.5 5[1] A power transfer state (with load) [1] - The maximum average current is 2 A. However, when removing the receiver, the power stage current protection limits the peak current at 5 A. 5. Ordering information Table 2.
