STMicro Introduces Battery Chargers With Enhanced Internal Protection For Handsets

STMicroelectronics has introduced what it describes as improved smaller-dimension circuit-protection devices to enable safer use of universal chargers. ST’s new ESDA8V2-1MX2 absorbs mains-borne surges containing up to 500W peak pulse energy, a level of protection which is said to be 30% higher than the current most popular surge protector. At the same time, the 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 is available immediately in sample quantities or for full production, priced at $0.11 for 10,000 pieces.
