Overview
LM3622 Lithium-Ion Battery Charger Controller February 2000 LM3622 Lithium-Ion Battery Charger Controller General Description The LM3622 is a charge controller for Lithium-Ion batteries.
This monolithic integrated circuit accurately controls an external pass transistor for precision Lithium-Ion battery charging.
The LM3622 provides a constant voltage or constant current (CVCC) configuration that changes, as necessary, to optimally charge lithium-ion battery cells.
Voltage charging versions (4.
1V, 4.
2V, 8.
2V, and 8.
4V) are available for one or two cell battery packs and for coke or graphite anode battery chemistry.
The LM3622 accepts input voltages from 4.
5V to 24V.
