STMicroelectronics Opens Way to reduce the environmental burden of millions of battery chargers
Supporting objectives to reduce the number of battery chargers discarded with portable devices such as cellphone handsets, GPS receivers, and personal media players, STMicroelectronics has introduced an improved smaller-dimension circuit-protection device to enable safer use of universal chargers. ST’s new ESDA8V2-1MX2 has 55% smaller footprint, measuring just 1.0 x 1.45mm, thereby realizing space savings for designers to implement extra functions or to further miniaturize the end product. The protection device also has a thinner profile of 0.55mm, compared to 0.7mm or 1.0mm for typical alternative devices.
Another benefit is a 50% reduction in leakage current, which reduces drain on the battery for improved performance and longer recharge intervals. The ESDA8V2-1MX2 from STMicroelectronics is available immediately in sample quantities or for full production, priced at $0.11 for 10,000 pieces.
