Part Number: BQ25720EVM Other Parts Discussed in Thread: BQ25720 Tool/software: Hi, Expert
I'm testing BQ25720 as following setup, but VSYS always drop when heavy load.
Test condition:
Vin=20V;
VSYS_min=12.3V
ISYS=0A to 6A;
IBAT=0A;
JP3=4S;
Test…
Thanks Tiger,
I mean, if my system want a stable system voltage all the time no matter charging or not, I may need another circuit to stablize the output system voltage from BQ25720 right?
Because I measured that the system voltage from BQ25720 may change…
Part Number: BQ25720EVM Hi Team,
What is the use of CHG_OK signal here. I simulated the same in PSPICE and unable to control the input voltage with CHG_OK pin.Help me out to understand the logic.

Hi team,
There are three questions I do not understand when I test the EVM without battery (the jumpers in the EVM are set as default).
1. In the boost forward mode (Vbus = 5V, Vsys = 10V), the bus voltage cannot be over 3A even…

Hi team,
When I tested the EVM without battery , I got two waveforms that I could not explain.
The waveforms and relative test conditions are shown below, and I want to know:
1.1. For PFM…
Part Number: BQ25720EVM Other Parts Discussed in Thread: BQSTUDIO , , BQ25720 Hi Experts,
Our customer has ev2300 and trying to configure a bq25720evm. He downloaded the latest version of bqstudio but unfortunately, there is no bq25720.bqz file to select…
Part Number: BQ25720EVM Hi
The customer purchase the BQ25720EVM, They want to set the Iac 10A and Iout 16.2A.
Could Q1-Q4 and Q5 support above current. If can not support Iac 10A and Iout 16.2A.
Please recommend the suitable MOSFET.
Waiting for your reply…

They customer test with BQ25720EVM,
After the adapter DC is set to 20V/6A current limiting input, the load can be increased to 50W without triggering VSYS_ UVP protection; Add the load to 60W will trigger VSYS_UVP.
When the…
Part Number: BQ25720EVM Hi Team,
Our customer is testing BQ25720EVM. Could you please tell me the function of RC network as shown in the screenshot.
Is it used to absorb voltage spikes? Why Q1 and Q4 don't need RC network? Thanks.
Best regards! …
