DATASHEET  
ISL9211A  
Charging System Safety Circuit

Rev 3.00  
November 5, 2014  
The ISL9211A is an integrated circuit (IC) optimized to provide  
a redundant safety protection to a Li-ion battery 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 N-channel MOSFET  
to remove the power from the charging system to the battery.  
In addition to the above protected parameters, the IC also  
monitors its own internal temperature and turns off the N-  
channel MOSFET when the temperature exceeds +150°C.  
Together with the battery charger IC and the protection module  
in a battery pack, the charging system using the ISL9211A has  
triple-level protection and is two-fault tolerant.  
Features  
• 24V Max Input Voltage  
• Supports Up To 2.0A Input Current  
• Fully Integrated Protection Circuit for Three Protected  
Variables  
• High Accuracy Protection Thresholds  
• User Programmable Overcurrent Protection Threshold  
• Responds To Input Overvoltage in Less Than 1µs  
• High Immunity of False Triggering Under Transients  
• Fault Indication for Various Fault Occurrence  
• Easy to Use  
The IC is designed to turn on the internal NFET slowly to avoid  
inrush current at power up but will turn off the NFET quickly  
when the input is overvoltage in order to remove the power  
before any damage occurs. The ISL9211A has a logic flag  
output to indicate a fault condition. The enable input allows  
the system to cut off the input power if needed.  
• Pb-Free (RoHS Compliant)
