Hi

The customer design with BQ24610, when the battery is not connected, ISET1 and ISET2 waveforms are found to be abnormal, as shown in Figures 1 and 2.

When the battery is connected, the output battery voltage is abnormal in figure 3.

BAT output waveform as below:

ISET as below:

Please help check it.

Thanks

    Hello Star,

    I have a few questions:

    Can you provide the schematic?

    What is the input voltage/current?

    What is the battery voltage/Charge current?

    ISET is an input, Is Vref abnormal? How are the vertical and horizontal set?

    Best Regards,

    Christian
