Description
The STEVAL-WLC38RX is an evaluation board based on the STWLC38 and designed for wireless power receiver application. The evaluation board allows its user to quickly start their 5W Qi-BPP and 15W Qi-EPP compatible wireless charging receiver projects.Through the I2C interface the user can access and modify different configuration parameters, and hence tailor the operation of the device to the needs of custom applications.Using an on-board USB-to-I2C bridge, the user can monitor and control the STWLC38 using the STSW-WPSTUDIO graphical user interface (GUI).
Features
- Up to 15 W output power
- Up to 5W output power in Tx mode
- Qi 1.3 inductive wireless standard communication protocol compliant
- High efficiency (98% typical) synchronous rectifier operating up to 800 kHz
- Low drop-out linear regulator with output current limit and input voltage control loop
- Adaptive Rectifier Configuration (ARC) Mode for enhanced spatial freedom
- 4 V to 12 V programmable output voltage
- Above 85% overall system efficiency
- 32-bit, 64 MHz ARM Cortex M0+ core with 32kB RRAM,16 kB SRAM,64kB ROM
- 10-bit A/D Converter
- Configurable GPIOs
- I2C Slave interface
- Multi-level ASK modulator, Enhanced FSK demodulator
- Output Over-Voltage clamping protection
- Accurate voltage/current measurement for Foreign Object Detection (FOD)
- On-chip thermal management and protections
- Flip chip 40 bumps (2.12mm x 3.32mm)
Typical applications
- Wireless Power Rx
