BQ24105-Q1: short circuit protection function

Part Number: BQ24105-Q1

Dear team,

Does our device support short circuit protection function? I didn't see such description for this in the datasheet.

Thanks & Best regards,

Sherry

  • Dear Sherry,

    The datasheet offers I_SHORT which occurs on the falling of V_IBAT. Please see the datasheet for more details.

  • Hi Mike,

    Thanks for your reply!

    In our datasheet I didn't see the short circuit detection mechanism. I see the I_short. When the Vbatt is smaller than 2V, there will be a short to battery, right? But if the Vbatt is smaller than 2V, it may also be that the power supply is removed. What is our short protection type, short to battery, or short to ground? Could you please help give more explanation?

    Thanks & Best Regards,

    Sherry

  • Dear Sherry,

    The protection is a shorted battery, meaning less than 2 V/cell, and will limit the current to Ishort. If the power supply is removed, there will be no charging. Please see Figure 5 for the Typical Charging Profile.

    Thanks,
