Hi,
The following E2E thread lead me to BQ4050 and BQ40z50. Can I please have some help with the implementation? https://e2e.ti.com…
Hi Chris,
BQ25708/710/713 are all our buck-boost charger, which can meet your requirements to support all the PD input voltages (5V, 9V, 15V and 20V) charging 1s~4s battery. The difference is BQ25708 (SMBus) only has the forward charging without OTG…
Hello Nadav,
The over-current protection for the BATFET cannot be disabled to prevent damage to the device. Other devices in the portfolio have similar OCP thresholds, like the bq25892, which is minimum of 9A before the OCP trips.
If your application…
Hi Chase, Please refer to the following FAQ. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/871078/faq-bq25710-bq25713-bq25713b-bq25700a-bq25703a-bq25708---schematic-review-design-tips Do they have an EV2400…
Hi Amir,
While the BQ24725A is capable of supporting a 12V adapter and is capable of supporting a 12V battery, it cannot charge a 12V battery from a 12V adapter. This is because the charging circuit is buck-only and there is a slight (maybe 0.5V)…
Hi Kiril, Please refer to the following FAQ: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/871078/faq-bq25710-bq25713-bq25713b-bq25700a-bq25703a-bq25708---schematic-review-design-tips Recommend testing and…
Hello Riccardo,
When everything is powered the gauge will start writing the the charge voltage and charge current, I have tested with bq40z50-R4 and bq25710 and when the gauge is configured it will start the charger when the VBUS is applied.
Sincerely…
Hi Kazuya-san, Please see the following FAQ. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1032726/faq-bq25700a-bq25703a-bq25708-bq25710-bq25713-bq25713b-bq25720-bq25723-bq25730-bq25731-which-buck-boost-charge…
Hi Dylan,
My interpretation of datasheet section 9.3.8 is that, when two-level ILIM (peak power mode) is enabled, the ILIM1, will be employed and will limit input current by reducing charging current.
With single-level ILIM, battery will start to…
Hi Suraj,
The BQ25710 can run off of a 1S (3.5-4.2V) cell, so the level of discharge on the battery should not be an issue. I set up the EVM with 5.0V on battery, no adapter, and JP2-4 set for 2S, and there was no issue with I2C communication.
As…
