LM3621
Single Cell Lithium-Ion Battery Charger Controller
General Description
The LM3621 is a full function constant voltage, constant
current (CVCC) lithium-ion (Li+) battery charger controller. It
provides 1% regulation accuracy over the specified tempera-
ture range without requiring the use of external precision
resistors. The IC controls five charge modes: conditioning,
fast, top-off, monitor and maintenance. In addition, the
LM3621 detects and flags defective batteries as well as over
current and over voltage fault events. The architecture of the
IC is based on high gain constant voltage and constant
current control loops.
The LM3621 is designed to control a switching charger, a
linear charger or an off-line ac adapter charger.
The LM3621 consists of a logic controller, precision bandgap
reference, wide bandwidth transconductance error amplifi-
ers, comparators, and an output buffer. The LM3621 is avail-
able in a 16-pin SOIC package and is specified over the
range of 0C to 70C.
