Batterilader IC til lavspændings genopladelige batterier
ROHM har udviklet batterilader IC, der er designet til brug i forbindelse med opladning af wearables og kompakte IoT-enheder med mere (in english).ROHM developed a battery charger IC - BD71631QWZ - designed to provide low-voltage charging of wearables like wireless ear buds and thin, compact IoT devices such as smart displays powered by rechargeable batteries.
Based on this market demand, ROHM developed a battery charger IC that supports low voltage charging of not only li-ion, but also new types of rechargeable batteries such as all-solid and semi-solid state. The BD71631QWZ achieves low voltage charging over a wide range from 2.0V to 4.7V by improving the stability of the internal circuit.
Additionally, original package technology results in a compact package just 0.4mm thickness, which is 60% lower than conventional products in market. This is contributing to smaller, thinner devices. In addition, each charging characteristic like charge/termination current can be set for CCCV charging, providing an optimal charging environment for thin, compact IoT and wearable devices utilizing the latest rechargeable batteries.
Going forward, ROHM will continue to contribute to providing greater application convenience by supplying more efficient charging solutions.
Application examples include:
- Devices equipped with low voltage and single-cell li-ion rechargeable batteries
- Wearables such as wireless ear buds, electronic pens, e-cigarettes, etc.
- Smart displays/tags and other compact IoT devices
