Charging System Safety Circuit  
Features  
The ISL9212A 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 ISL9212A has triple-level  
protection and is two-fault tolerant.  
• Fully Integrated Protection Circuit for Three Protection  
Variables  
- User Programmable Overcurrent Protection Threshold  
- Input Overvoltage Protection in Less Than 1µs  
- Battery Overvoltage Protection  
• High Immunity of False Triggering Under Transients  
• High Accuracy Protection Thresholds  
• Warning Output to Indicate the Occurrence of Faults  
• Enable Input  
• Thermal Enhanced DFN Package  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
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 ISL9212A has a  
logic warning output to indicate the fault and an enable input  
to allow the system to remove the input power.  
Applications  
• Cell Phones  
• Digital Still Cameras  
• PDAs and Smart Phones  
• Portable Instruments  
• Desktop Chargers

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.
