Wireless charging ICs offer dual mode power capability for quick charge

Dual-mode Wireless Power Consortium (WPC) Qi 1.2 and AirFuel Alliance (PMA) SR1E medium power 15W capability has been added to the Semtech TS80000 wireless charging portfolio.
The ICs support the increased battery capacity for quick charging smart phones, tablets, phablets, and medical and industrial devices.
The company’s medium power wireless charging technology can be integrated into existing portable devices as well as infrastructure and automotive applications. The TS80K devices can support both receiver and transmitter applications. The company also provides reference designs and evaluation kits to implement the technology.
Key feature are the scalability. According to the company, this is the only product on the market that supports from 100mW low power wearable solutions to 100W high power solutions for industrial tools, medical equipment and “connected” furniture applications.
Multi-mode receiver and output power from 100mW to 20W allow compatibility between all transmitters supporting any of the three industry standards.
Multi-mode transmitter for all power levels, from 100mW to 40W allow embedded charging capability in furniture, vehicles and public venues that can support all three standards based on a single, cost-effective platform, says the company.

Compact wristwatch form factor FPGA is smaller than MCUs

Based on the iCE40 Ultra FPGA, Lattice Semiconductor offers a development platform for designing low-power wearable devices.
The FPGA uses a package that is 60% smaller than alternative microcontrollers, says the company. It also supports a low power standby mode for always-on functionality, suitable for wearables that need to operate for days between charges.
Hardware features and sensors supported include a 1.54inch display, MEMS microphone, high-brightness LED, IR LED, BLE module and 32Mbyte of flash memory. There is also support for sensors capable of measuring heart rate/SpO2, skin temperature, and pressure as well as an accelerometer and gyroscope.
The wrist watch form factor measures 1.5 x 1.57 x 0.87inches, with a wrist strap and a built in battery.
A user guide and several demos are included to showcase parallel RGB to MIPI DSI bridging, health monitor, pedometer, IR transmitter or flashlight functions.
