LM3641 Product details

Description

The LM3641 Lithium Protection Integrated Circuit resides inside a 3.6V Lithium-Ion battery pack consisting of a single cell or multiple parallel cells.

Features

n Automatic battery disconnect when the cell is over-charged or over-discharged. n Maximum cell voltage for MOSFET conduction is factory programmable between 4.0V and 4.4V with a ± 25 mV tolerance (0˚C to +60˚C). n Minimum cell voltage for MOSFET conduction = 0.57.
VMAX ± 3.5% (0˚C to +60˚C). n Internal 4 mΩ current sense resistor provides ± 0.5A maximum accuracy for detection of overcurrent faults. The maximum charge and discharge current is factory programmable between 1A and 5A. A si.
