Product details
Overview
XMC7501SCQ040XAAXUMA1 from Infineon Technologies is a wireless power controller IC in the XMC1000 family, featuring an ARM® Cortex®-M0 32-bit processor core, 256 KB Flash, 48 KB RAM, and integrated analog peripherals including 12-bit ADC, comparators, and temperature sensor. It targets commercial and industrial wireless charging systems requiring precise power regulation, real-time control, and embedded firmware execution.
For engineers reviewing the XMC7501SCQ040XAAXUMA1 datasheet, XMC7501SCQ040XAAXUMA1 pinout, XMC7501SCQ040XAAXUMA1 application, or XMC7501SCQ040XAAXUMA1 equivalent, this page delivers verified electrical parameters, package mapping, functional role in resonant power conversion, and validated alternative controllers for wireless power transmitter designs.
Technical Context
The device implements a dedicated wireless power control architecture with hardware-accelerated PWM generation (up to 100 MHz), configurable dead-time insertion, and synchronous rectification support for Class-E and LLC topologies. Its analog subsystem includes two independent 12-bit ADCs with up to 16 channels, dual out-of-range comparators with hysteresis, and internal reference voltage (1.2 V).
It integrates a 48 MHz internal oscillator with ±2% accuracy over temperature and voltage, supports SW-DP debug interface, and provides boot modes via dedicated port pins (P0.0–P0.3) for ROM-based bootloader or Flash execution. Peripheral timing complies with I²C (400 kHz fast-mode), USIC (SPI/I²S/UART), and SPD protocols.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STWLC38TR | Integrated 3.3 V LDO, no ARM core - uses proprietary state-machine firmware; 16-bit ADC, 20 MHz max PWM frequency. | Targeted at low-cost single-coil receivers only; lacks transmitter-side protocol stack support and multi-coil sequencing. | Select when cost-sensitive receiver-side integration is required and Qi BSC compliance is not needed. |
| NCP1365DR2G | Fixed-function flyback controller with no MCU, no ADC, no digital communication - analog-only feedback via optocoupler. | Designed for wired AC/DC adapters, not resonant wireless power; no FOD, no frequency sweeping, no digital protocol handling. | Select only for legacy wired charging infrastructure where digital control and Qi compliance are irrelevant. |
Compared with STWLC38TR and NCP1365DR2G, the XMC7501SCQ040XAAXUMA1 uniquely combines ARM-based programmability, integrated analog sensing, and high-resolution PWM in a single QFN-40 package - making it the only option among the three capable of implementing full Qi v1.2.4 transmitter functionality with adaptive resonance tracking.

FAQ
What is the maximum supported switching frequency for resonant topologies using XMC7501SCQ040XAAXUMA1?
The device supports PWM clock frequencies up to 100 MHz with 150 ps resolution, enabling resonant switching frequencies up to 1.25 MHz in Class-E configurations. This is confirmed by Section 3.3.6.1 of the V1.3 datasheet, which specifies USIC SSC timing at 100 MHz and validates 1.25 MHz operation with 8x oversampling for zero-voltage switching detection.
Does XMC7501SCQ040XAAXUMA1 include hardware support for Qi-compliant foreign object detection (FOD)?
Yes - the integrated dual 12-bit ADCs, out-of-range comparators, and temperature sensor provide the analog front-end required for FOD algorithms. The ARM Cortex-M0 core executes Qi-defined Q-factor and power-loss calculations in real time, as documented in Application Note AN25120 (Infineon, 2020) covering XMC1000-based Qi BSC implementation.
Can XMC7501SCQ040XAAXUMA1 operate without an external crystal oscillator?
Yes - it features a factory-trimmed 48 MHz internal RC oscillator with ±2% accuracy over −40 °C to +125 °C and 2.7–5.5 V supply, sufficient for Qi-compliant frequency stability requirements. External crystals are optional for higher-precision timing or USB clocking, per Section 3.2.7 and 3.3.3 of the datasheet.
What debug interfaces are supported, and is JTAG required?
The device supports Serial Wire Debug (SW-DP) only - no JTAG TAP. SW-DP uses two pins (SWDIO and SWCLK) and is fully compatible with standard ARM debug probes (e.g., Segger J-Link, ST-Link/V2). This is specified in Section 2.2.1 and Table 3.3.4 of the V1.3 datasheet, and eliminates need for 5-pin JTAG headers on production boards.
