Wireless connectivity SoC company Telink and energy harvesting IC developer Nowi have launched an energy autonomous wireless connectivity module. The TLSR8273-M-EH combines Telink’s top of the line multi-protocol connectivity SoC with Nowi’s industry leading energy harvesting PMIC.

This new product offering, say the companies, enables additional energy harvesting use-cases by further reducing bill of material size, cost and complexity. By providing low-power wireless connectivity, energy autonomy and power management all-in-one, the new module becomes a complete solution, which is designed to allow users to:

  • Reduce BOM and size – Thanks to the compact size and unique design of Nowi chipsets, the bill of material is significantly reduced. With a minimum need for external components (no inductors required) and their integration of both energy harvesting and power management features, the assembly size is also greatly reduced, which makes for a more cost-effective and smaller module.
  • Reduce supply chain complexity – By integrating many features -including connectivity, energy harvesting, power management and USB charging-into one complete solution, only 1 module is needed instead of several chips, making for simpler purchasing and supply chain processes.
  • Improve user-friendliness – By removing the need for battery swaps, Telink’s Energy Harvesting Connectivity Module enables the creation of hassle-free products. Nowi’s power management solutions answer the needs of a market which is frustrated by frequent battery swaps. According to a recent Qualtrics study, 89% of respondents would like an alternative to battery-powered TV remote controls. A large majority chose self-charging remotes as the most attractive alternative option.
  • Improve the environmental impact of new products – This solution addresses the needs of TV ODMs and OEMs who cater to the new generation of environmentally conscious consumers. The industry is increasingly moving towards sustainable alternatives and reducing its reliance on billions of polluting primary batteries.

With combined wireless connectivity and energy harvesting on a compact footprint, the module makes batteryless operations possible for a wide range of IoT applications. In addition, the module is compatible with Telink’s SDKs, making it easier for customers to upgrade their products with minimum effort.

One of the most fitting applications for the module, say the companies, is TV remote controls that harvest energy from indoor lighting using a PV cell. To that end, Telink also provides a reference design based on the module for such remote control products.

Samples of the wireless connectivity module are available now. Nowi and Telink teams will be available at IBC, the international conference for broadcasting in Amsterdam, from September 9-12, where the module and remote control samples will be showcased.
