Hello Ning,
Thank you for providing correct information regarding the GUI. Now we have another problem related to charger register. We have used HPA 172 USB interface adapter along with BQ2419XEVM-GUI v1.5.0.1 software to configure charger register. For…
Hi team,
Where can I get the schematic files for the BQ2419xEVMs? Specifically, the BQ24195EVM.
Furthermore, are these in a format that can be opened in OrCAD? If not, which program is needed?
Best,
Part Number: BQ27531-G1 Other Parts Discussed in Thread: BQ24192
Hello,
I am using a BQ studio to perform learn cycle on BQ27531-G1 gas gauge along with BQ24192 charger. I would like to change charge current to 2048 mA in Chrgr_current_Reg2 but in Charger…
Attie,
1. Referring to 8.3.2.1 Narrow VDC Architecture (Applicable when valid VBUS is present), the device deploys Narrow VDC architecture (NVDC) with BATFET separating system from battery. The minimum system voltage is set by REG01[3:1]. Even with a…
Part Number: BQ24193 Other Parts Discussed in Thread: BQ24190 , BQ24196 , BQ24195 , BQ24192 Hi,
A very similar question has been asked before, but we cannot see that the answer provides the full info we look for.
We are interested in evaluating BQ24193,…
Part Number: BQ24193 Other Parts Discussed in Thread: BQ2419XEVM Dear Ti support
I'm Sesumi from Japan.
I have a question about charge operation.
After precharge operation, I saw an abnoromal operation, in which current reached about 1A~2A for about…
Hi,
1.In order to improve light-load efficiency, the device switches to PFM control at light load when battery is below minimum system voltage setting or charging is disabled. Please refer to Fig 39 on the d/s.
2. The device may operate normally without…
Hi Mark,
You can order a BQ24190 Evaluation Module from: www.ti.com/.../BQ2419XEVM
I have two recommendations for ways to mitigate the high frequency noise that you are seeing:
1. Add a 1nF Cap at PMID to GND. Use a X7R, 0402 and place it as close…
Hello Yaita-san,
The efficiency data is taken using the bq2419xEVM which is similar to the application schematic on the datasheet, with the addition of the test points for evaluation purposes on the EVM. The voltage measurements are done as close as…
Hi Arsadhusaim,
The TPS65185 GUI cannot be updated, but it can update the firmware on a USB-to-GPIO. If the LED is not on at all, the adapter may be bricked and I am not exactly sure how to correct this. The USB adapter uses a TUSB3210, and there might…
