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