I have a customer looking to use the BQ2000, in a new audio product. This product will be powered by 2 AA batteries. They had a couple questions:
1) Can I use the BQ2000 to charge both batteries in series? I assume I simply need to use a resistor divider and connect half the overall battery voltage at the
BAT input.
2) The customer wants to know if they can be able to use alkaline batteries, as well. How does this charger respond if alkaline batteries are installed? Are there any safety issues?
3) I do not plan to install the temperature sensing resistor, but am still concerned about safety issues. If I were to limit the charge current to roughly 50ma, could I be assured that a faulty battery would not present a fire hazard?
