BQ40Z50-R3-DEVICE-FW: bq40z50 R3 SOH Based Degradation

Part Number: BQ40Z50-R3-DEVICE-FW

Hi Expert:

I have one questoin about voltage degrade function.

when I enable SOH_degrade bit alone, the function works.

However, if I enable both SOH_degrade and cycle_degrade bits, voltage no step down even reach to either SOH degrade condition or cycle degrade condition. Is it a normal behavior?

    Hi Shane,

    It should work with either or both set. The order of degradation is if the configuration bits [RUNTIME_DEGRADE], [CYCLE_DEGRADE], and [RTORCC] are all set,

    then degradation occurs according to the runtime or cycle count criteria first met.
