Multi-Cell Li-ion Battery Pack Analog Front-End
The ISL94201 is an analog front end for a microcontroller in
a multi-cell Li-ion battery pack. The ISL94201 supports
battery pack configurations consisting of 4-cells to 7-cells in
series and 1 or more cells in parallel. The ISL94201 provides
an internal 3.3V voltage regulator, and cell voltage monitor
level shifters.
Using an internal analog multiplexer the ISL94201 provides
monitoring of each cell voltage plus internal and external
temperature by a separate microcontroller with an A/D
converter. Software on this microcontroller implements all
battery pack control functionality.
