Nowi unveil energy harvesting PMIC with a cold start feature

Dutch semiconductor company, Nowi, extends its energy harvesting and power management portfolio with the Diatom chipset. The 4.0 x 4.0mm Diatom (NH16D3045) is an energy harvesting PMIC, which has a wide power input range from micro W to mW and a fast MPPT (maximum power point tracking) for efficient energy harvesting.

It is designed to extract the power output of a wide range of energy harvesters to charge a variety of energy storage elements such as rechargeable batteries or supercapacitors. 

The cold start feature enables batteryless applications, which helps companies reduce maintenance costs, as well as a more sustainable and easier to use option, the company said.

Diatom caters to the need for increased integration in order to lower implementation cost, size and complexity whilst improving performance, added Nowi. It combines integrated energy harvesting and power management into a single product and has regulated output, over-voltage protection and USB charging. 

Diatom enables power autonomy in a variety of low power applications, from the smart home to industry 4.0 and retail applications. It can be used in IoT devices, electronic shelf labels (ESLs), to smart wearables such as smart bands, glasses, and consumer electronics like remote controls, tags. 

According to Nowi, Diatom perpetually powers devices with clean ambient energy, simplifies the design process and lowers the threshold to develop energy autonomous products. 

Simon van der Jagt, CEO at Nowi, said that the inductorless design and integrated power management functionalities will contribute to reduced implementation cost and area  required, and make new designs possible.

Semiconductor company, Nowi was founded in 2016, based in Delft, the Netherlands. It ha regional offices in the US and in Shanghai. 

Nowi has developed energy harvesting power management ICs (PMICs) that combine harvesting performance with small assembly footprint and low bill of materials (BoM) cost.
