Product details
Overview
MWPR1124ZVHT from NXP Semiconductors is a wireless power receiver controller SoC integrating an Arm® Cortex-M0+ MCU, 512 KB Flash/128 KB SRAM, and a Bluetooth® Low Energy v4.2 transceiver operating at 2.4 GHz with -95 dBm sensitivity and programmable output power (-30 to +3.5 dBm), designed for bidirectional communication between wireless power receivers and transmitters in multi-coil charging systems.
For engineers reviewing the MWPR1124ZVHT datasheet, MWPR1124ZVHT pinout, MWPR1124ZVHT application, or MWPR1124ZVHT equivalent, key selection considerations include its integrated DC-DC converter supporting buck/boost/bypass modes, 16-bit ADC with 500 kSPS capability, AES-128 hardware acceleration, and 48-pin Laminate QFN (7 × 7 × 0.98 mm, 0.5 mm pitch) package optimized for compact wireless charging modules.
Technical Context
The MWPR1124ZVHT implements a direct-conversion 2.4 GHz BLE transceiver with on-chip balun and single-ended RF port, supporting up to two simultaneous hardware BLE connections and MBAN band operation (2360–2400 MHz). Its radio subsystem includes dedicated BLE Link Layer hardware with dual connection engines and GFSK modulation at 1 Mbps.
System-level integration includes a 48 MHz Arm Cortex-M0+ core, 32.768 kHz crystal oscillator for RTC timing, and nine low-power modes including VLLS0 (182 nA), enabled by a configurable DC-DC converter that supports input voltages from 0.9 V (boost mode) to 4.2 V (buck mode) across industrial temperature range (-40 to 105 °C).

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power receiver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MWPR1024IZVHT | Same die, identical BLE radio, MCU, memory, and peripherals; differs only in factory-programmed MAC address and flash content lock configuration. | Targeted for standard (non-Premium) Qi implementations without PC0 authentication; lacks 40-bit MAC sub-address pre-provisioning. | Select MWPR1024IZVHT for cost-sensitive designs where Qi Premium features are not required. |
| STMicroelectronics STWLC38 | Dedicated wireless power receiver IC (no integrated BLE radio); requires external MCU and BLE module for out-of-band communication. | Used in simpler, lower-cost receivers where BLE telemetry is implemented separately; lacks integrated resonant frequency tracking and FOD algorithms. | Choose STWLC38 only if BLE functionality is handled externally and system-level integration is less critical than BOM cost. |
Compared with MWPR1124ZVHT, MWPR1024IZVHT offers identical hardware but reduced security provisioning for non-Premium use cases, while STWLC38 shifts BLE and control logic to external components-increasing board area, power consumption, and firmware complexity.

FAQ
What is the primary function of the MWPR1124ZVHT in a wireless charging system?
The MWPR1124ZVHT serves as the complete system-on-chip for wireless power receiver units, performing real-time voltage/current measurement, resonant frequency tracking (100–145 kHz), foreign object detection, and secure Bluetooth Low Energy v4.2 communication with the transmitter unit. It eliminates the need for separate MCU, radio, and power management ICs in PRU designs.
Does the MWPR1124ZVHT support both Qi and proprietary wireless charging standards?
Yes, the MWPR1124ZVHT supports Qi Premium certification (including Power Class 0 and 1) through hardware-accelerated BLE Secure Connections and factory-provisioned 40-bit MAC sub-addresses. Its programmable resonant frequency tracking and flexible DC-DC operation also enable implementation of proprietary multi-coil topologies beyond Qi specifications.
What are the key power management capabilities of the MWPR1124ZVHT?
The MWPR1124ZVHT integrates a configurable DC-DC converter supporting buck (2.1–4.2 V input), boost (0.9–1.795 V input), and bypass modes. It achieves 182 nA current in VLLS0 low-power mode, 6.8 mA typical Rx current, and 6.1 mA Tx current at 0 dBm-enabling operation from coin cells, alkaline batteries, or regulated 19.5 V PRU outputs.
How does the MWPR1124ZVHT implement Foreign Object Detection (FOD)?
The MWPR1124ZVHT implements FOD using its 16-bit ADC to monitor real-time current and voltage deviations during power transfer, combined with thermal sensing and algorithmic analysis of coil impedance changes. This hardware-assisted detection halts power delivery within milliseconds when metallic or conductive objects are identified-meeting Qi safety requirements.
Is the MWPR1124ZVHT pin-compatible with the MWPR1024IZVHT?
Yes, the MWPR1124ZVHT and MWPR1024IZVHT share identical 48-pin Laminate QFN packaging, pinout, electrical characteristics, and functional architecture. They differ only in factory-programmed security attributes (e.g., MAC address provisioning and flash lock configuration), making them drop-in replacements at the PCB level.
