E-PEAS unveils ultra-efficient battery chargers to target new set of products 

July 8, 2021 1:27 pm

Addressing the need for streamlined power management solutions for energy harvesting hardware, e-peas has unveiled a new family of battery charger devices.

While the company’s existing power management ICs (PMICs) offer direct power delivery to the application, as well as the charging of energy storage elements (such as Li-Ion batteries or super-capacitors), the AEM10900, AEM10300 and AEM30300 are fully dedicated to the charging function. This allows them to be employed in situations that need a simpler implementation, where there are space or cost constraints that need to be considered. The PMICs are able to achieve zero quiescent current draw from the battery – meaning that if energy harvesting stops for a prolonged period of time, the energy stored into the battery will not be wasted supplying the PMIC.

Working in conjunction with a single-cell photovoltaic panel, the highly-integrated AEM10900 PMIC boost converter is optimised for solar-based energy harvesting implementations. Through its super-fast power point tracking (MPPT) functionality specially set for objects in movement, this device is able to ensure that it gets the most energy from the ambient illumination available – so as much as possible can be stored. In addition, it has a 250mV cold start capability, which means it can commence with charging the battery even when light intensities are very low. AEM10900 introduces an I2C interface to minimise the pin count and to offer a larger set of potential configurations. It offers an array of features, including battery thermal protection, a joule counter to let the user know the amount of energy harvested, plus a shipping mode in which the battery cannot be charged. Key applications from this PMIC will be wearable consumer products and body-worn medical monitoring equipment.

Geoffroy Gosset, CEO & co-founder stated, “As e-peas’ business matures and we continue to gain ever greater commercial traction, we must look to provide a more expansive portfolio of PMIC options to the market. Following on from in-depth consultations with our customer base, it became clear that having compact solutions for charging only was going to be of real value. With these newly introduced devices we will now be able to better serve the wearable, healthcare, consumer and industrial sectors, supporting them with technology that fully meets their needs in terms of performance, size and price point.”
