Frequently Asked Questions
What are the requirements for connecting the battery sense input (BAT)?
The input impedance to end-to-end should be at least 200kΩ and less than 1 MΩ.
How can I safely stop fast charging if necessary?
Fast charge is inhibited by setting the Charge inhibit input (INH) pin high.
What methods are used for battery termination during fast charging?
Termination occurs via Peak voltage detection (PVD), negative delta voltage (-ΔV), or maximum time limit.
Besides fast charge, what charging modes does the bq2002E/G support?
It optionally supports top-off, pulse-trickle, and trickle control in addition to fast charge.
