The bq2005s Fast-Charge IC provides comprehensive fast charge control functions together with high-speed switching power control circuitry on a monolithic CMOS device for sequential charge management in dual battery pack applications.

Does fast charge really work?

Fast charging technologies are most effective when your battery is less than 50% full but has a diminishing impact on charge time once the battery passes 80%. Incidentally, constant current charging is the least detrimental period to the battery's long-term health.

What package is BQ2005S available in?

It is available in a 20-Pin SOIC package.

How can the fast charge begin ?

The fast charge may begin with the application of the charging supply, replacement of the battery, or switch depression. For safety, fast charge is inhibited unless/until the battery temperature and voltage is within configured limits.
