ISL9212
Charging System Safety Circuit
The ISL9212 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 ISL9212 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 ISL9212
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.
