The devices operate as both a high power receiver and a transmitter for rapid power transfer and power sharing with foreign object detection (FOD) and other proprietary safety IPs.

The company’s proprietary high-voltage technology is paired with mixed signal design and is intended for integration in a range of applications, such as wearable devices and small appliances to larger ones like smartphones and tablets. The IC is WPC Qi 1.2.4-compliant and compatible with all Qi-certified devices on the market.

The ICs have integrated low-impedance, high-voltage synchronous rectifier and low drop-out linear regulator for high efficiency and low power dissipation. These characteristics are critical for applications that are sensitive to unnecessary heat build-up, notes the company.

Firmware and platform parameters can be customised using an I²C interface. Configuration can be programmed into the embedded OTP while additional firmware patching is also available to enhance the IC’s application flexibility.

The company offers a selection of models in the family, from 5.0 to 20W. For lower power designs, there is the STWLC68JRH.

The STWLC68JRH is in production and available in a 3.29 x 3.7 x 0.6mm WLCPS 72-bumps 0.4mm pitch package.

Two evaluation-boards are also available. The STEVAL-ISB68RX is for standard 5.0W applications and the STEVAL-ISB68WA simplifies prototyping for PCBA-sensitive 2.5W low power applications. Both have header connectors for easy access to the GPIOs and other important signals. A USB dongle is included for configuring the device registers.
