Charging System Safety Circuit
The ISL9209B 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 ISL9209B 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 ISL9209B 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.

rDS(ON) Measured at 500mA, 4.3V < VIN < 5.5V - 250 450 mΩ
Pin Descriptions
VIN (Pin1, 2)
The input power source. The VIN can withstand 30V input.
GND (Pin 3)
System ground reference.
WRN (Pin 4)
WRN is an open-drain logic output that turns LOW when any
protection event occurs.
NC (Pin 5, 6, 12)
No connection and must be left floating.
EN (Pin 7)
Enable input. Pull this pin to low or leave it floating to enable
the IC and force it to high, which will disable the IC.
VB (Pin 8)
Battery voltage monitoring input. This pin is connected to the
battery pack positive terminal via an isolation resistor.
ILIM (Pin 9)
Overcurrent protection threshold setting pin. Connect a
resistor between this pin and GND to set the OCP threshold.
OUT (Pin 10, 11)
Output pin.
EPAD
The exposed pad at the bottom of the TDFN package for
enhancing thermal performance. Must be electrically
connected to the GND pin.
