Consumer versus industrial batteries for wireless applications

The world is truly wireless, and battery-powered devices are ubiquitous, powering everything from consumer electronics to all sorts of industrial applications connected to the Industrial Internet of Things (IIoT).

Consumer electronics are typically powered by alkaline batteries, consumer grade primary lithium (non-rechargeable) cells, or consumer grade rechargeable Lithium-ion (Li-ion) batteries. There is also a growing number of industrial applications that require long-life power to operate maintenance-free for decades while delivering two-way wireless communications.

Qi-compliant inductive wireless power receiver for 5W applications

The STWLC68 is an integrated Wireless Power Receiver suitable for portable applications and capable of managing up to 5 W of output power. The chip has been designed to support Qi 1.2.4 specifications for inductive communication protocol and Base Power Profile (BPP).

The STWLC68 shows excellent efficiency performance thanks to the integrated low-loss synchronous rectifier and the low drop-out linear regulator: both elements are dynamically managed by the digital core to minimise the overall power dissipation over a wide range of output load conditions.
