Other Parts Discussed in Thread: BQ40Z50
Hi,
BQ40Z50 has many types of protection.
And they can set delay time and recovery delay time.
Could you tell me the accuracy (±xx％) information for each set delay time, recovery delay time, etc. for the set value?
Customers need that information to design their apps.
We would like to know the following protection accuracy information.
CUV—Cell Undervoltage /Delay
CUVC—Cell Undervoltage /Delay
Threshold Rec Temp /Delay
OCC1—Overcurrent In Charge 1 /Delay
OCC2—Overcurrent In Charge 2 /Delay
OCC—Overcurrent In Charge Recovery / Recovery Delay
OCD1—Overcurrent In Discharge 1 /Delay
OCD2—Overcurrent In Discharge 2 /Delay
OCD—Overcurrent In Discharge Recovery /Recovery Delay
AOLD—Overload in Discharge /Counter Dec Delay, Recovery, Reset
ASCC—Short Circuit In Charge /Counter Dec Delay, Recovery, Reset
ASCD—Short Circuit in Discharge /Counter Dec Delay, Recovery, Reset
OTC—Overtemperature in Charge /Delay
OTD—Overtemperature in Discharge /Delay
OTF—Overtemperature FET /Delay
UTC—Under Temperature in Charge /Delay
UTD—Under Temperature in Discharge /Delay
HWD—Host Watchdog /Delay
PTO—Precharge mode Time Out /Delay
CTO—Fast Charge Mode Time Out /Delay
CHGV—ChargingVoltage /Delay
CHGC—ChargingCurrent /Delay, Recovery Delay
PCHGC—Pre-ChargingCurrent /Delay, Recovery Delay
SUV—Safety Cell Undervoltage /Delay
SOV—Safety Cell Overvoltage /Delay
SOCC—Safety Overcurrent in Charge /Delay
SOCD—Safety Overcurrent in Discharge /Delay
SOT—Overtemperature Cell /Delay
SOTF—Overtemperature FET /Delay
Open Thermistor—NTC Thermistor Failure /Delay
QIM—QMax Imbalance /Delay
VIMR—Voltage Imbalance At Rest /Delay, Duration
VIMA—Voltage Imbalance Active /Delay
CFET—CHG FET Failure /Delay
DFET—DFET Failure /Delay
FUSE—FUSE Failure /Delay
AFER—AFE Register /Delay Period, Compare Period
AFEC—AFE Communication /Delay Period
2LVL—2nd Level OV /Threshold time
