SLUUCH2 March 2021 BQ40Z50-R2
The BQ40Z50-R4 device can inhibit the start of charging at high and low temperatures to prevent damage of the cells. This feature prevents the start of charging when the temperature is at the inhibit range; therefore, if the device is already in the charging state when the temperature reaches the inhibit range, a FET action will not take place even if FET Options[CHGIN] = 1. High Temperature charge inhibit can be disabled by setting [HT_INHIB_DIS].

Trip | Not charging AND (ChargingStatus()[HT] = 1 OR (ChargingStatus()[OT] = 1 AND [HT_INHIB_DIS] = 0) OR ChargingStatus()[UT] = 1 | ChargingStatus()[IN] = 1 ChargingStatus()[SU] = 0 ChargingVoltage() = 0 ChargingCurrent() = 0 OperationStatus()[XCHG] = 1 if FET Options[CHGIN] = 1 |
