SLUUCP8 June 2024 BQ41Z50
The BQ41Z50 device can stop charging if it measures a difference between the requested ChargingCurrent() and the delivered current from the charger. This protection is designed to recover by a discharge event; therefore, CHGC:Recovery should be set to a negative value in data flash.
Status | Condition | Action |
---|---|---|
Normal | Current() < ChargingCurrent() + CHGC:Threshold | SafetyAlert()[CHGC] = 0 |
Alert | Current() ≥ ChargingCurrent() + CHGC:Threshold | SafetyAlert()[CHGC] = 1 BatteryStatus()[TCA] = 1 |
Trip | Current() ≥ ChargingCurrent() + CHGC:Thresholdfor CHGC:Delay period | SafetyAlert()[CHGC] = 0 SafetyStatus()[CHGC] = 1 BatteryStatus()[TCA] = 0 OperationStatus()[XCHG] = 1 |
Recovery | SafetyStatus()[CHGC] = 1 AND Current() ≤ CHGC:Recovery Threshold for CHGC:Recovery Delay time | SafetyStatus()[CHGC] = 0 BatteryStatus()[TCA] = 0 OperationStatus()[XCHG] = 0 |
