FeaTures DescripTion
32V, 2A µModule Li-Ion/
Polymer Battery Charger
The LT M
®
8061 is a high efficiency 32V, 2A µModule
®
standalone Li-Ion battery charger. It is optimized for
one and two-cell packs, with fixed float voltage options:
4.1V, 4.2V, 8.2V and 8.4V. The LTM8061 provides a
constant-current/constant-voltage charge characteristic,
with maximum charge current up to 2A. A precondition
feature trickle charges a depleted battery, and bad battery
detection provides a signal and suspends charging if a
battery does not respond to preconditioning.
The LTM8061 can be configured to terminate charging
when charge current falls to one-tenth the programmed
maximum current or to use an internal timer if a time-
based termination scheme is desired. Once charging is
terminated, the LTM8061 enters a low current standby
mode. An auto-restart feature starts a new charge cycle
if the battery voltage drops 2.5% from the float voltage,
or if a new battery is inserted into a charging system.
The LTM8061 is packaged in a thermally enhanced, com
-
pact (9mm × 15mm × 4.32mm) over-molded land grid
array (LGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8061 is
RoHS
compliant.
