Frequently Asked Questions
How does the bq2002C handle fast charge termination?
Fast charge can be terminated using negative delta voltage (-ΔV) or peak voltage detection (PVD).
What method is needed for monitoring battery temperature?
The TS pin requires a resistor-thermistor network to develop the temperature sense voltage.
How can I temporarily inhibit fast charging?
Applying a high signal to the INH (Charge inhibit) pin will suspend the fast charge process.
What is required for monitoring single-cell battery potential inputs?
The BAT input must be connected via a high-impedance resistor divider network.
