BQ2005S Features
* Sequential fast charge and conditioning of two NiCd or NiMH nickel-cadmium or nickel-metal hydride battery packs
* Hysteretic PWM switch-mode current regulation or gated control of an external regulator
* Easily integrated into systems or used as a stand-alone charger
* Pre-charge qualification of temperature and voltage
* Direct LED outputs display battery and charge status
* Fast-charge termination by temperature /D time, -DV, maximum voltage, maximum temperature, and maximum time
* Optional top-off and pulse-trickle charging
BQ2005S Advantage
The advantages of BQ2005S Fast-Charge IC is below:
Integration of closed-loop current control circuitry allows the BQ2005S to be the basis of a cost-effective solution for stand-alone and system-integrated chargers for batteries of one or more cells. Switch-activated dis-charge-before-charge allows BQ2005S-based chargers to support battery conditioning and capacity determination. High-efficiency power conversion is accomplished in the BQ2005S is a hysteretic PWM controller for switch-mode regulation of the charging current. The BQ2005S may alternatively be used to gate an externally regulated charging current.

Frequently Asked Questions
What is BQ2005S?
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.
