BQ25616: Discharge current parameters missing from datasheet

Part Number: BQ25616


DATASHEET: SLUSDF7A – JANUARY 2020 – REVISED FEBRUARY 2022

Dear all,

multiple reading throughout of this paper it seems to me that there is a parameter and value missing from the document.

9.3.9.5.3 System Overcurrent Protection When the system is shorted or significantly overloaded (IBAT > IBATOP) and the current exceeds BATFET overcurrent limit, the BATFET latched off. The BATFET latch can be reset with VBUS plug-in.

So, the highlighted parameter IBATOP is never referenced with the appropriate value in this datasheet. Also, a good side information would be if there is some kind of blanking time for the detection of the IBATOP while there is a transient on the load side of the IC.

Until later,

kind regards!

  • Hi,

    1. It refers to ISYS_OCP_Q4 spec on the d/s below. This will be updated in the next revision of the d/s.

    2. The battery discharge over-current limit protection has typical 100us deglitch time.

    Thank you,

    Ning.
