The device has a hardware-based cell overvoltage protection with adjustable threshold and delay time.
| Status | Condition | Action |
|---|---|---|
| Normal | Voltage() < Protector OVP Threshold | SafetyStatus()[HCOV] = 0 |
| Trip | Voltage() ≥ Protector OVP Threshold for Protector OVP Delay Time | SafetyStatus()[HCOV] = 1 OperationStatus()[XCHG] = 1 Turn off CHG FET |
| Recovery | SafetyStatus()[HCOV] = 1 AND Voltage() ≤ HCOV:Recovery for HCOV:Recovery Delay | SafetyStatus()[HCOV] = 0 OperationStatus()[XCHG] = 0 |
