LM3641 Lithium-Ion Battery Pack Protection Circuit
General 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.
The IC controls the ON/OFF state of a pair of low threshold N-channel power MOSFETs placed in series with the battery cell(s).
The purpose of this MOSFET pair is to protect the cell(s) from inadvertent electrical over-stress.
The IC compares the cell voltage against internally programmed minimum and maximum limits.
Transient voltage faults of approximately 1.
25 seconds are tolerated.
The IC also monitors the...
