The ISL9208 is an overcurrent protection device and analog
front end for a microcontroller in a multi-cell Li-ion battery
pack. The ISL9208 supports battery pack configurations
consisting of 5-cells to 7-cells in series and 1 or more cells in
parallel. The ISL9208 provides integral overcurrent
protection circuitry, short circuit protection, an internal 3.3V
voltage regulator, internal cell balancing switches, cell
voltage monitor level shifters, and drive circuitry for external
FET devices for control of pack charge and discharge.
Selectable overcurrent and short circuit thresholds reside in
internal RAM registers. An external microcontroller sets the
thresholds by setting register values through an I2C serial
interface. Internal registers also contain the detection delays
for overcurrent and short circuit conditions.
