Hello,
The BQ25622E device is designed to work with an inductor in the range of 1uH to 2.2uH. I have attached the BQ25622EVM User's Guide document below in case you wish to reference the inductor selected by TI to be used on the evaluation board for this…
Hi Ethan,
Please see relevant GUI and oscilloscope capture of 5V 3A charging with the BQ25622EVM. When input supply can provide the required current there is no large oscillations observed and IBAT ADC outputs expected value. This confirms the behavior…
Hi Simon,
Firstly, generally speaking for best performance regarding SYS regulation whenever a battery is not connected to your system charge needs to be disabled via either EN_CHG bit or /CE pin. This allows the device to have faster response to a sudden…
Hi Stanley,
Please see my comments below.
Let me first address question 6. If customer does not require boost they should also consider BQ25622E. It will be very similar to BQ25622, but without the boost mode feature and will therefore be less expensive…
Hi Dejan,
The below waveform is taken on the BQ25622EVM with 2.2kohm resistors for SCL/SDA pullup to SYS rail. SDA repeatedly driving low has no impact on SYS. The point being that I2C communication should not result in significant increase in load current…
How can I use a BQ25622EVM from TI with the USB2ANY?, the board comes with a connector for this.
Which software can I use to configure the registers?
Thank you
Hi Nandor,
Please help to confirm if my understanding of your test setup is correct. You have both a DC load and the buck boost converter connected to SYS in the testing where you are modifying RILIM.
For the the 2nd and 3rd case the behavior is unexpected…
