short circuit protection, overcurrent protection.

The protective plate using Japan’s Ricoh rechargeable lithium iron phosphate battery protection IC

1) high-accuracy voltage detection circuit

2) terminal of the charger using high voltage devices;

3) Built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit);

4) MOS transistor can be controlled by a battery charge and discharge;

5) low standby current consumption.

Function and Notice:
1, the lithium battery with protection board according to the wiring diagram connection,
when the battery voltage is overcharge and over-discharge voltage between the voltage,
and P +, P- charging 1 second, P + and P- output voltage of the battery voltage.

2, the battery charge function: between P + and P- plus charger to charge the battery,
the battery voltage charge to overcharge detection voltage (4.25 ±0.025V),
the protection circuit to cut off the charging path, to achieve overcharge protection.

3, Battery over-discharge protection: in between the P + and P- connected load to the battery discharge
when the battery voltage drops to over-discharge voltage (2.7  0.05V), the protection circuit,
shut off the discharge path to achieve the over-discharge protection.

4, Short circuit protection: When the P + and P- short circuit protection circuit will act quickly in 5-50uS,
cut off access, short-circuit protection.

5, Overcurrent protection function: When the V- terminal voltage of (0.15 ± 0.02V),

the protection circuit will act quickly in 6.7-13.9ms, cut off access, overcurrent protection
