ISL9209
Charging System Safety Circuit
The ISL9209 is an integrated circuit (IC) optimized to provide
a redundant safety protection to a Li-ion battery from failures
of a charging system. The IC monitors the input voltage, the
battery voltage, and the charge current. When any of the
three parameters exceeds its limit, the IC turns off an internal
P-channel MOSFET to remove the power from the charging
system. In addition to the above protected parameters, the
IC also monitors its own internal temperature and turns off
the P-channel MOSFET when the temperature exceeds
140°C. Together with the battery charger IC and the
protection module in a battery pack, the charging system
using the ISL9209 has triple-level protection and is two-fault
tolerant.
The IC is designed to turn on the internal PFET slowly to
avoid inrush current at power up but will turn off the PFET
quickly when the input is overvoltage in order to remove the
power before any damage occurs. The ISL9209 has a logic
warning output to indicate the fault and an enable input to
allow the system to remove the input power.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
