What to pay attention to when designing 18650 lithium battery protection board

What to pay attention to when designing 18650 lithium battery protection board 1. Overcharge detection voltage: Under normal conditions, Vdd gradually rises to the voltage between VDD and VSS when the CO terminal changes from high level to low level. 2. Overcharge release voltage: In the charging state, Vdd gradually decreases to the voltage between VDD and VSS when the CO terminal changes from low level to high level. 3. Overdischarge detection voltage: Under normal conditions, Vdd gradually decreases to the voltage between VDD and VSS when the DO terminal changes from high level to low level. 4. Overdischarge release voltage: In the overdischarge state, Vdd gradually rises to the voltage between VDD and VSS when the DO terminal changes from low level to high level. 5. Overcurrent 1 detection voltage: In the normal state, VM gradually rises to the voltage between VM and VSS when DO changes from high level to low level. 6. Overcurrent 2 detection voltage: In the normal state, VM rises from OV to the voltage between VM and VSS when the DO terminal changes from a high level to a low level at a speed of 1ms or more and 4ms or less. 7. Load short-circuit detection voltage: In the normal state, VM starts from OV and rises to the voltage between VM and VSS when the DO terminal changes from high to low at a speed of 1μS or more and 50μS or less. 8. Charger detection voltage: In the over-discharge state, VM gradually decreases with OV to the voltage between VM and VSS when DO changes from low level to high level. 9. Current consumption during normal operation: Under normal conditions, the current flowing through the VDD pin (IDD) is the current consumption during normal operation. 10. Over-discharge current consumption: In the discharging state, the current (IDD) flowing through the VDD terminal is the over-current discharge current consumption.
