Products with triple protection

 

1.Overcharge protection circuit

Protection IC detects battery voltage when the voltage reaches 4.25V (assuming battery

overcharge point is 4.25V) then start overcharging protection ,MOSFET switches to cut off,

and then cut-off charge.

 

 

2.Over-discharge protection circuit

Protection IC detects battery voltage when the voltage reaches the discharge voltage detection point

(assumed to 2.75V or 2.55V) will start over-discharge protection, the MOSFET switch cut off,

turn off discharge.

 

3.Short-circuit protection circuit

When the discharge current is too large or short circuit conditions, protection IC will start

over-current protection (short circuit), increases the internal resistance of the battery to

stop battery discharge.
