Need a recommended fuel gauge for a parking meter that is powered using a single lithium battery(~4V, 500mA) which is charged by a Primary non-rechargeable battery and solar panels.

Hi,

We are evaluating the BQ27Z561EVM for the rechargeable battery. We would like to use only the 1 wire HDQ protocol for the interface to the host. Is there another gauge that you recommend for the nonrechargeable battery so we can also use connect using the same 1-wire HDQ interface?
