Product details
Overview
WLC1150-68LQXQ from Infineon is a 50W wireless power transmitter IC with integrated USB Type-C PD 3.1 controller, Arm® Cortex®-M0 MCU (44 MHz, 128 KB Flash, 16 KB RAM), and dual-stage inverter gate drivers. It delivers proprietary high-power charging and Qi v1.3.x EPP/BPP compliance, supports 4.5–24 V input, and integrates buck-boost regulation for wide-input applications. Used in industrial docking stations and high-power charging pads.
For engineers reviewing the WLC1150-68LQXQ datasheet, WLC1150-68LQXQ pinout, WLC1150-68LQXQ application, or WLC1150-68LQXQ equivalent, key selection criteria include integrated PD 3.1 + PPS support, on-chip FOD and thermal management, programmable inverter control (frequency/duty/voltage), and dual-stage topology flexibility without external DC-DC conversion.
Technical Context
The WLC1150 implements a dual-mode wireless power control architecture: baseband ASK/FSK modulation/demodulation for Rx-Tx communication and real-time inverter control via four PWM outputs with slew-rate-controlled high-/low-side gate drivers. Its integrated buck-boost controller regulates VBRG across 5–20 V input, enabling direct DC or USB PD/PPS sourcing without front-end conversion.
On-chip resources include an 8-bit SAR ADC for temperature sensing and current monitoring, configurable protection logic (adaptive FOD, OCP/OVP/OTP), and I²C/UART interfaces for host and security IC (e.g., OPTIGA™ Trust Charge) integration - all coordinated by the embedded Cortex-M0 running proprietary protocol stacks and Qi-compliant firmware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wireless Output Power | 50 W using Infineon proprietary high-power protocol; enables single-coil industrial-grade charging without multi-phase complexity. |
| USB PD Support | Full USB PD 3.1 compliance with Programmable Power Supply (PPS); eliminates need for external PD controller in Type-C powered designs. |
| Input Voltage Range | 4.5 V to 24 V; accommodates both USB PD adapters and fixed DC supplies - no external buck-boost required for 20 V operation. |
| MCU Core | Arm® Cortex®-M0 @ 44 MHz with 128 KB Flash, 16 KB RAM, 32 KB ROM; hosts full wireless stack, PD firmware, and custom application logic. |
| Integrated Protection | Adaptive foreign object detection (FOD), overcurrent (OCP), overvoltage (OVP), and overtemperature (OTP) with internal sensor and ADC feedback loop. |
| Operating Temperature | −40 °C to +105 °C extended industrial range; validated for sustained 50 W operation in thermally constrained enclosures. |
| Communication Interfaces | I²C (2 channels), UART, SWD; supports secure authentication via OPTIGA™ Trust Charge and debug/programming during development. |
Pinout & Package
Package: 68-lead QFN, 8.0 × 8.0 × 0.65 mm body with 5.7 × 5.7 mm exposed thermal pad (LD68B).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HG1_0 / LG1_0 / HG2_0 / LG2_0 | Half-bridge gate drivers (primary stage) | Drive external N-channel MOSFETs in first inverter bridge; support frequency/duty-cycle/voltage control for precise power regulation. |
| HG1_1 / LG1_1 / HG2_1 / LG2_1 | Half-bridge gate drivers (secondary stage) | Enable dual-stage topology; allow independent control of second inverter for wide-input voltage adaptation (e.g., 5–20 V). |
| VBRG / VBRG_DIS | Buck-boost regulator reference and enable | VBRG sets regulated gate drive voltage; VBRG_DIS disables regulator for low-power standby or fault recovery. |
| ASK_P / ASK_N / ASK_DEMOD | Current/voltage-based ASK demodulation inputs | Interface with external dual op-amp to decode Rx-to-Tx communication signals; essential for Qi-compliant bidirectional handshaking. |
| CC1 / CC2 / DP / DM | USB Type-C configuration channel and data lines | Directly negotiate USB PD contracts (including PPS), detect cable orientation, and manage legacy protocols (QC 2.0/3.0, AFC). |
| TEMP_FB / NTC | Temperature feedback input | Connects to NTC thermistor for closed-loop thermal management; triggers OTP shutdown when die temperature exceeds 105 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB PD 3.1 + PPS controller | Removes external PD IC, reduces BOM count by ≥3 components, and enables dynamic voltage/current adjustment during charging. |
| Programmable dual-stage inverter control | Supports both single-stage (20 V DC) and dual-stage (5–20 V) topologies - eliminates need for discrete buck-boost IC in wide-input systems. |
| On-die adaptive FOD with Q-factor monitoring | Detects metallic objects via resonant frequency shift and coil loss measurement - meets IEC/EN 62368-1 safety requirements without external sensors. |
| Embedded Cortex-M0 with 128 KB Flash | Enables field-upgradable firmware for protocol updates (e.g., Qi v1.3.x EPP), custom coil tuning, and OEM-specific feature differentiation. |
| Integrated fan buck controller (VFAN) | Drives cooling fan directly from VBRG rail; maintains interface surface temperature <45 °C during continuous 50 W delivery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless transmitter controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STWBC2-HP | Supports 50 W Qi EPP only; lacks integrated USB PD controller and requires external PD IC for Type-C input. | Targeted at Qi-certified consumer chargers; not suitable for proprietary 50 W protocol or USB PD-native systems. | Select when Qi compliance is mandatory and USB PD integration is handled externally. |
| MP-A21 Transmitter Controller | Standalone analog controller with no embedded MCU; relies on external host processor for protocol stack and FOD logic. | Used in cost-sensitive, fixed-function transmitters where firmware customization is unnecessary. | Select for simple, non-upgradable designs with minimal BOM cost priority over feature flexibility. |
Compared with STWBC2-HP and MP-A21, WLC1150-68LQXQ uniquely integrates USB PD 3.1 + PPS, a field-programmable Cortex-M0, and dual-stage inverter control - enabling single-chip 50 W proprietary and Qi-compliant solutions without external controllers or protocol licensing dependencies.

No. The device integrates a fully functional Arm® Cortex®-M0 MCU with 128 KB Flash and 16 KB RAM, capable of running complete wireless charging stacks, USB PD firmware, and custom application logic without external host processing. External MCUs are optional only for advanced system-level coordination.
What USB PD protocols does WLC1150-68LQXQ support beyond PD 3.1?
In addition to full USB PD 3.1 and PPS, it natively supports QC 2.0/3.0, AFC, and Apple 7.5 W legacy charging protocols - all managed by the on-chip PD controller without external ICs. Licensing for QC/AFC must be obtained separately by the end customer.
