Hello Jason,

The bq4050 is a gauge which uses the CEDV algorithm. Whereas bq40z50 and bq40z80 are gauges which use impedance track algorithm.
The bq40z50 can handle from 2-4 cells and single cell. The bq40z80 handles 2-4 cells and more than 4 cells.

For more details refer to the ti.com website for each device.

Here's a good thread on CEDV vs IT algorithm: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1106909/bq4050-cdev-vs-it?tisearch=e2e-sitesearch&keymatch=CEDV%2520vs%2520IT%2520algorithm#
