Functional Description
The AAT3682 is a linear charger designed for single
cell lithium-ion/polymer batteries. It is a full-featured
battery management system IC with multiple levels
of power savings, system communication, and pro-
tection integrated inside. Refer to the block diagram
above and the flow chart and typical charge profile
graph (Figures 1 and 2) in this section.
Cell Preconditioning
Before the start of charging, the AAT3682 checks
several conditions in order to maintain a safe charg-
ing environment. The input supply must be above
the minimum operating voltage, or under-voltage
lockout threshold (V
UVLO
), for the charging
sequence to begin. Also, the cell temperature, as
reported by a thermistor connected to the T
S
pin,
must be within the proper window for safe charging.
