Qi-compliant dual mode wireless power receiver for up to 15W applications

Overview

TopologyWireless Power Transfer
Input voltage5-12 V
Output 112 V / 1.25 A
IC revision1

Description

The STWLC38 is an integrated Wireless Power Receiver suitable for wearable/hearable and smart phone applications and can supply up to 15 W of outputpower. The chip has been designed to support Qi 1.3 specifications for inductive communication protocol, 5W Baseline Power Profile and 15W Extended PowerProfile. STWLC38 shows excellent efficiency performance thanks to the integrated low-losssynchronous rectifier and the low drop-out linear regulator: both elements are dynamically managed by the digital core to minimize the overall power dissipation over a wide range of output load conditions.

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

  • Wearable/Hearables TWS
  • Medical and healthcare equipment
  • Smartphones
