Circuit Diagram Li-Ion Battery Charger using IC LM3622

Robotronicdiagram. - This is Circuit Diagram Li-Ion Battery Charger using IC LM3622 like in Figure 1 below. The main component in this circuit diagram is IC LM3622. With this circuit schematic we can make the LM3622 which is an excellent Li-Ion charger, controller device. The IC has been designed for generating a constant current at constant voltage, a basic prerequisite for all Li-Ion batteries. The IC may be configured for charging a single Li-Ion cell or a pack of many.

Circuit diagram like in Figure 1 above is Circuit Diagram Li-Ion Battery Charger using IC LM3622. According Homemade-circuits site describe that It is generally advised that a Li-ion battery should be charged with utmost care and caution as these type of batteries are prone to instant damages or explosions if the specified charging measures are not employed. Here we discus a Li-ion charger circuit which has been specifically designed for charging all types Li-Ion Batteries very safely and without any considerations.

The circuit using the IC LM3622 can be fed with voltages right from 5 to 24V depending upon the charging needs and the connected battery. The IC does not require any precision external resistors for implementing the functions. Moreover, the IC has a negligible drain of less than 200nA of current from the battery in the absence of an input voltage.

The in built circuitry of the chip accurately regulates the charging current through the principle of temperature compensated band-gap reference. The current is regulated, however its done via an external current sensing resistor.
