Part Number: BQ2419XEVM Other Parts Discussed in Thread: EV2400 Hi Team,
I understand from the thread below that the BQ2419x EVM works with USB-to_GPIO, EV2300 or EV2400.

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: BQ24195 Other Parts Discussed in Thread: USB-TO-GPIO2 , BQ2419XEVM , USB2ANY Hello TI team,
I just tried to connect the evaluation board BQ24195EVM-193 to PC via USB-TO-GPIO2 interface adapter.
When I have connected the interface adapter…

I had used 2 evaluation modules bq28z610evm and bq24725evm to simulate my single cell li-ion battery charge…
Part Number: BQ24192 Other Parts Discussed in Thread: BQSTUDIO , BQ2419XEVM , EV2400 Hi team,
Can you have a look at the following customer inquiry?
We were able to successfully complete the learning cycle for the application battery on the VitaGuard…
Hey sesumi,
We are not familiar with the magOH RED board. The only board design we support is the BQ2419xEVM.
For starters, the inductor value is not recommended size of 2.2uH. You are using 3.3uH. Additionally, the size of the inductor along with…
Hey Nicky,
Again, I do not see anything unacceptable on your schematic.
One thing to check is the saturation current rating your inductor.
Additionally, a layout may also be helpful.
If you do not have an E-load, do you potentially have a power…
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…
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…
