Part Number: BQ24005
Other Parts Discussed in Thread: BQ24004, BQ24040

Hello,

The BQ24004/5/6 series support 2 series cells. is there an equivalent part for a 1-cell support?

Thank you,

Gaurav

    Hello Gaurav

    The BQ2400X series are very old devices would a newer device such as the BQ24040 would in your application?

    What are your requirements, input voltage, charge currents and others?

    Hi Bill,

    The charge current should be 1A or more. input is variable and can be adjusted accordingly (from a separate power supply). This charger needs to interface with a host controller and hence it clearly needs to indicate faults such as precharge timer fault, fast charge timer fault, temperature faults etc. The BQ2400X has a very clear indication of various faults on the STAT1 and STAT2 pins and is more fault indication friendly than the BQ24040. 

    Is there any linear charger with adjustable output through a feedback resistor network?

    Thank you,

    Gaurav

    Hi Gaurav

    BQ2408X is family of devices with STAT1 / 2 pins and will provide more definition of the Charge State, see Table 3 of data sheet.

    All of the Linear regulators are fixed outputs, 4.2V is the most common, some higher voltages are available. 

    Adjustable output are available in some switching converters.
