High Power Li-Ion Charger W/I-Path Management  
ISL9230  
Features  
The ISL9230 is a fully integrated high input voltage single-cell  
Li-ion battery charger with power path management function.  
This charger performs the CC/CV charge function required by  
Li-ion batteries. The charger can withstand an input voltage up to  
26V but is disabled when the input voltage exceeds 6.6V OVP  
threshold. The input current limit and charge current are  
programmable with external resistors. When the battery voltage  
is lower than 3.0V, the charger preconditions the battery with  
10% of the programmed charge current. When the charge  
current reduces to the end-of-charge (EOC) current level during  
the CV charge phase, the EOC indicator (CHG) will toggle to a  
logic high to indicate the end-of-charge condition.  
• Complete Charger for Single-Cell Li-ion/Polymer Batteries  
• Current Path Management Optimize for Charge and System  
Currents  
• Intelligent Timeout Interval Based on Actual Charge Current  
• 1% Charger Output Voltage Accuracy  
• Programmable Input Current Limit  
• Programmable Charge Current  
• NTC Thermistor Input  
• Complies with USB Charger  
• Charge Current Thermal Foldback for Thermal Protection  
• Trickle Charge for Fully Discharged Batteries  
• 26V Maximum Voltage at VIN Pin  
The ISL9230 uses separate power paths to supply the system  
load and the battery. This feature allows the system to  
immediately operate with a completely discharged battery. This  
feature also allows the charge to terminate when the battery is  
full while continuing to supply the system power from the input  
source, thus minimizing unnecessary charge/discharge cycles  
and prolonging the battery life.  
• Power Presence and Charge Indications  
• Ambient Temperature Range: -40°C to +85°C  
• 16 Ld 3x3 TQFN Package  
Two indication pins (PG and CHG) allow simple interface to a  
microprocessor or LEDs.  
• Pb-Free (RoHS Compliant)  
Applications  
• Mobile Phones  
• Blue-Tooth Devices  
• PDAs  
• MP3 Players  
• Stand-Alone Chargers  
• Other Handheld Devices
