最新的BQ78350-R1相对78350老版本有什么改进呢?

官方页面没有找到什么答案,有相关说明吗?

  • bq78350-R1 ver 1.03 build 22
    =======================================
      - Fixed AFE comm timeout issue with "AFE alert clear sooner" change causing reset.
      - Fixed AFE_R which may trigger when load present bit in system control 1 register is set and
              CHG FET is off, default setting would prevent the AFE_R failure.

    bq78350-R1 ver 1.02 build 21
    =======================================
       - Changed address of DynamicPower() cmd to 0x4c from 0x50
       - Fixed LEDCHG/LEDRCA option to work for LCD display as well

    bq78350-R1 ver 1.02 build 20
    =======================================
      - Added option to latch OCD safety (OCDL), works same as AFE latching feature.
      - Added option to turn off LCD in sleep mode by setting LCD_SLEEP_DIS in LED configuration register
      - Added feature to clear the AFE Columb counter alert signal sooner, a timer checks every 5ms if alert
        is detected and clear it
      - Fixed Overload/short circuit detection not working in sleep mode under some cases
      - Added bq4050 base code changes including
        * wake from sleep on system Present change to update FET control, will go back to sleep if sleep
          conditions are satisfied
        * fix max saturation current

    bq78350-R1 ver 1.01 build 18
    =======================================
      - [Bug #1559] - Set TCA/TDA/OT flag for OTF safety failure and SOTF PF failure
      - [Bug #1564] - Fixed AFE Overide safety failure issue

    bq78350-R1 ver 1.01 build 17
    =======================================
     - Based on RTM version 0.06 build 16
     - Modified initial Remcap estimation to be based on Learned FCC instead of
       Qmax Pack
     - Synch AFE and Gauge FET control
     - Fixed Display not triggring if button held for long period of time
     - Add option to require FC=1 to set VDQ
        This require that a charge termination prior to allowing VDQ to be set.
     - RSOCL active in all mode
     - EDV sample counter is not reset, EDV should trigger only after N samples in a row
       however the sample counter is not reset if the voltage goes back above the threshold
     - Added battery removal option to clear current protection
     - Added option to turn off both fet for overcurrent in charge/discharge
        protection
     - Added option to initialize RemCap to a percentage value of OCV correlation
        upon exit from reset
     - Enabled Auto Ship Mode
     - Added system in sleep feature
     - Lifetime voltage resolution changed from 20mV to 1mV
     - Added FET temperature and safety
     - Added  gauge internal tempperature measurment
     - Added Dynamic power cmd (0x50) to return calculated power
     - Added AFE override as Temporary safety protection in addition to PF
     - PWRM is driven low BEFORE entering shutdown
     - Fix bq769x0 Gain correction for 3.3 LDO
     - Clear SAFE flag on initialization


    =======================================
    bq78350 ver 0.06 build 16
    =======================================
     -[bug #833] Fix rsoc drop at onset of discharge with VFLT_EN

    =======================================
    bq78350 ver 0.06 build 15
    =======================================

    Changes:
     - [bug #813] Fix self discharge tracking in sleep
     - [bug #810] Change [PCHG_POL] to default to zero to match EVM hardware
     - [bug #809] Fix corruption on programming auth and unseal codes
       - Previous code only worked if auth key programmed immediately after unseal
         keys. Otherwise the key/code not programmed would be corrupted.
     - [bug #800] Fix safety code to shut off PCHG FET when using external I/O

    =======================================
