BQ25150EVM: Having issues using BQStudio and the EVM to charge >10mA

Mike Credelle

Part Number: BQ25150EVM
Other Parts Discussed in Thread: BQSTUDIO, EV2400,

It seems like no matter how I set the registers I am stuck at 10mA. I am using an EV2400 and BQStudio 1.3.86 with charger_1_00-bq25150.bqz as a configuration. Any suggestions?

Hello,

When you initiate a read using BQstudio, do you see "Device OK"?

Are you using the BQ25150EVM?

Yes, the ADC registers also update to logical values.

Hello Mike,

Can you please remove the J17 Vpullip jumper and check again to see if it works. Make sure Vio is shorted to VDD on J11

Hello Mike,

Can you post your schematic?

Do you have /CE pulled low on your board?

Hello Mike,

Were you able to try pulling /CE low?

yes I tried that, I didn't post the schematic because I was just using the EVM and you already have that. It's not an issue for me anymore because I am now using the GDK instead and it is working.
