Part Number: BQ27530EVM
Other Parts Discussed in Thread: EV2400

Hi,

I am using BQ27530EVM with 3.7v 7800mAH ( Note : I am not using EV2400).

We have tried to power it from both 5V 2A power supply and with USB port and from the J2 input , both fuel gauge and charger is enabled on the board but the battery doesn't get charged.

Below is our Jumper settings:

1. JP5 is Charger enabled (ON)
2. JP4 is Gauge enabled (ON)
3. JP1 is installed
4. JP3 is high enabled (for input on J2)

Kindly guide us.

Thanks

Hi Yatish,
You will need an ev2400 to send commands to the gauge and properly configure data flash to enable charging.

Hi Onyx,

Thanks for the quick response.

For now I will purchase EV2400 to enable the charging in BQ27530EVM but we are planning to use the bq27530-G1 fuel gauge and bq24160/1 for one of the power management applications to industrial device in that case how do we enable the charging without EV2400 or is it mandatory to use EV2400 circuitry in production pcb also?.

Kindly guide us.

Thanks

Once you configure your gauge correctly, you will be able to extract a golden image of that working configuration that you will program on multiple devices. pls revise the EVM user guide and TRM for the device to understand the proper configuration settings.
i hope this helps
Thanks
