Product details
Overview
NXQ1TXL5/101J from NXP Semiconductors is a fully integrated, Qi Version 1.2–compliant low-power wireless charging transmitter IC for 5 V input systems, delivering up to 8 W output power with <10 mW standby consumption including device detection, housed in a 32-pin HVQFN32 (5 × 5 mm) package, and designed for cost-sensitive smartphone and wearable charging applications.
For engineers reviewing the NXQ1TXL5/101J datasheet, NXQ1TXL5/101J pinout, NXQ1TXL5/101J application, or NXQ1TXL5/101J equivalent, key selection criteria include Qi v1.2 compliance without FOD, ultra-low standby power, USB-powered operation, CoolFlux™ DSP-based ASK demodulation, and drop-in PCB compatibility with NXQ1TXH5 layouts.
Technical Context
The NXQ1TXL5/101J implements a full-bridge power stage with integrated gate drivers and on-chip current/voltage sensing, controlled by a CoolFlux™ DSP core performing dual-channel ASK demodulation for Qi receiver communication. It supports Smart Power functionality that dynamically scales output power in response to supply voltage droop.
Unlike the NXQ1TXH5, the NXQ1TXL5/101J omits Foreign Object Detection (FOD) circuitry and associated configuration registers, reducing BOM count and simplifying tuning-only two external resistors are required for basic coil matching, and no FOD calibration is needed.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless charging transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXQ1TXH5/101J | Includes full FOD, I²C programmability, and additional safety registers; same pinout and package | Required for WPC Qi certification; supports dynamic FOD tuning and temperature monitoring | Select when Qi certification, NTC integration, or field-upgradable firmware is mandatory |

FAQ
Does NXQ1TXL5/101J support Qi certification?
No, the NXQ1TXL5/101J is Qi Version 1.2 compliant in core communication and power delivery but excludes Foreign Object Detection (FOD) circuitry required for full WPC Qi certification. It is intended for cost-sensitive, non-certified applications where system-level safety is managed externally. The NXQ1TXL5/101J shares the same silicon platform and RF behavior as the certified NXQ1TXH5/101J, differing only in FOD disablement and register lock-down.
What is the standby power consumption of NXQ1TXL5/101J?
The NXQ1TXL5/101J achieves <10 mW standby power, including active analog and digital ping for device detection. This ultra-low value is enabled by CoolFlux™ DSP sleep modes and dedicated low-power oscillators. Measured per WPC test conditions (no receiver present, 5 V supply), it supports Energy Star and EU CoC Tier 2 efficiency requirements for wireless chargers without additional power-gating circuitry.
Can NXQ1TXL5/101J replace NXQ1TXH5/101J on an existing PCB?
Yes - the NXQ1TXL5/101J uses identical pinout, package (HVQFN32, SOT617-3), and footprint as the NXQ1TXH5/101J. No PCB layout changes are needed. However, FOD-related external components (e.g., sense resistors, NTC path) become unused and may be omitted in new designs. Firmware and I²C initialization code must be updated to skip FOD register writes, as those addresses return NACK.
What power supply range does NXQ1TXL5/101J support?
The NXQ1TXL5/101J operates from 4.5 V to 5.5 V DC, making it compatible with standard USB 2.0/3.0 ports, USB wall adapters, and USB-C PD sources with fixed 5 V output. Its Smart Power feature monitors VDD and autonomously scales output power downward if supply voltage falls below 4.75 V, preventing instability during transient load events without external supervision.
How is communication handled between NXQ1TXL5/101J and Qi receivers?
The NXQ1TXL5/101J uses amplitude-shift keying (ASK) modulation with dual-channel demodulation performed entirely within its embedded CoolFlux™ DSP. This enables robust packet decoding from Qi receivers across varying coupling conditions and coil geometries. No external demodulator or comparator is required - the DSP outputs decoded control messages directly to the internal state machine for real-time power adjustment and handshake management.
