May 1, 2017 4-to 6-Cell Li-ion Battery Management Analog Front-End
The ISL94208 battery management IC is designed for use with a
microcontroller and features an analog front-end with
overcurrent protection for multi-cell Li-ion battery packs. The
ISL94208 supports battery packs consisting of four to six cells in
series and one or more cells in parallel. Features Software selectable overcurrent protection levels and variable
protect detection times
-Using an internal analog multiplexer, the ISL94208 allows a
separate microcontroller with an A/D converter to monitor each
cell voltage plus internal and external temperature.
The ISL94208 provides integral overcurrent and short-circuit
protection circuitry, an internal 3.3V voltage regulator, internal
cell balancing switches, and drive circuitry for external FET
devices for control of pack charge and discharge. Related Literature 4 discharge overcurrent thresholds
