I'd like to find out which fuel gauge chip is mounted in a battery pack.The device type I read in the chip is 0x4500. The hardware version is 0x0001.
The datasheets and user manuals I've read don't give the values one should read in the chip.Is there a list of device types somewhere ?
That id refers to the bq40z50, you will need to send 0x02 to 0x00 to confirm the fw.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Batt:
Thanks for your asnwer.What do you mean by "send 0x02 to 0x00" ?
The firmware bytes are 45 00 01 06 00 24 00 03 85 02 00 (in hex format).
Is there a detailed explanation of the meaning of these bytes somewhere ?
In reply to Nicolas Pinault:
That's a command sent from bqstudio to check the fw version. Please refer to the TRM. If you are using bqstudio just click the fw version command in the commands tab.
I've installed bqstudio. I'm waiting for the EV200 interface now.
