ISL9212B
Charging System Safety Circuit
The ISL9212B is an integrated circuit (IC) optimized to
provide a Li-ion battery redundant safety protection 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
die temperature exceeds +140°C. Together with the battery
charger IC and the protection module in a battery pack, the
charging system using the ISL9212B 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 input overvoltage is detected in order to
remove the power before any damage occurs. The
ISL9212B 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.
