LTM8061  
32V, 2A µModule Li-Ion/  
Polymer Battery Charger  
FEATURES  
DESCRIPTION  
The LTM®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 detec-  
tion provides a signal and suspends charging if a battery  
does not respond to preconditioning.

Wide Input Voltage Range: 4.95V to 32V  
(40V Absolute Maximum)  
Float Voltage Options:  
n
1-Cell: 4.1V, 4.2V  
2-Cell: 8.2V, 8.4V  
n
Programmable Charge Current: Up to 2A  
n
User-Selectable Charge Termination: C/10 or  
Onboard Termination Timer  
n
Dynamic Charge Rate Programming/Soft-Start Pin  
n
Programmable Input Current Limit  
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.

APPLICATIONS  
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.
