Part Number:BQ40Z50-R1
Hi Fuel Gauge Team,
Good morning, I'm working with a customer that is using the BQ40Z50-R1 in their design and is looking to do testing by simulating a battery.
A couple questions with this:
1. Can the device communicate without a battery/voltage on the BAT/VCx pins? The device is failing to communicate to a EV2400 in this case.
2. What is the best way to test the RSOC using a voltage or current source? When attaching the device to a power supply and changing the voltage, the RSOC isn't changing - as part of this, 10k resistors are being used in place of cells (maybe the impedance need to be closer to an actual cell?)
Thank you and please let me know if you have any questions!
Regards,
~John
