BQ25713: deglitch time question

Part Number: BQ25713
Other Parts Discussed in Thread: BQ25700

Hello

          REG0x32[2] is set ACOC value that is 1.33 or 2 times to ILIM2. For BQ25713 datasheet, Deglitch time to trigger is 250ms. But on description is 100uS as below. BQ25700 is 250us. Which deglitch time to trigger ACOC is correct?  

       Another question, while set REG0x01[2]=1. what is efficiency？

    Hey Patrick,

    I will look into this. 

    The first answer is a typo in the units; they should be "us", rather than "ms". However, I will verify whether 100-us or 250-us is the correct value.

    For the second question, I will start by saying that the efficiency data in Out of Audio mode is not available for this device, and that as a controller the efficiency data is highly dependent on the external component selection (MOSFETs, Inductors, etc). From testing however, the OOA power loss only becomes a factor in the region up to 50mA of system load current. The largest power loss difference seen between the two operating modes was around 5mA of load current, resulting in an 82mW difference when in OOA and not in OOA. 

    Again, this information should be taken with the caveat that this was a single instance of testing, with an EVM used for a metric. It is in no way representative of your results, which could vary.

    Regards,

    Joel H
