Description
The main I C adopt the original “ricoh” import components.
Have overcharge, discharge, over current, short circuit protected function,
use as in a variety of capacity of 3.7 V lithium batteries.Adopt NSK protected ICs,
VISHAY, AOS, IR high quality MOSFET, FR – 4 plank,
low temperature coefficient and excellent design, fine workmanship,complete testing.Small size,
suitable for many occasionswith high integration,
low cost requirements, ensure the battery pack absolutely safe and reliable.
Feature
Built-in high precision voltage detection circuit.
Connect to the charger terminals which using high pressure device.
Built-in three over current detection circuit (1 over current, 2 over current ,load short circuit)
Through the MOS tube ,it can control the battery charging and discharging;
Low standby current consumption.
Properties of the lithium battery protected board

Function
Connect the lithium battery with protected board according to the wiring diagram,
when the battery voltage is between the charging pressure and discharge voltage,
and the P +, P – charging after 1 seconds,
the output voltage P + and P – is the same as the battery voltage.
Notice
After connect to the battery correctly,
If no voltage for output end, please use charger to activated the protected board.
Package include
1Xprotected board.
