The ISL78693 is an integrated single-cell Li-ion or Li-polymer  
battery charger capable of operating with an input voltage  
as low as 2.65V (cold crank case). This charger is designed to  
work with various types of AC adapters or a USB port.  
Features  
• Complete charger for single-cell Lithium chemistry batteries  
• Integrated power transistor and current sensor  
• Reverse battery leakage 700nA  
The ISL78693 operates as a linear charger when the AC  
adapter is a voltage source. The battery is charged in a  
Constant Current/Constant Voltage (CC/CV) profile. The charge  
current is programmable with an external resistor up to 1A.  
The ISL78693 can also work with a current-limited adapter to  
minimize the thermal dissipation.  
• 1% initial voltage accuracy  
• Programmable CC current up to 1A  
• Charge current thermal foldback  
• NTC thermistor interface for battery temperature alert  
• Accepts CV and CC types of adapters or USB bus power  
• Preconditioning trickle charge  
The ISL78693 features charge current thermal foldback to  
ensure safe operation when the printed circuit board’s thermal  
dissipation is limited due to space constraints. Additional  
features include preconditioning of an over-discharged battery,  
an NTC thermistor interface for charging the battery in a safe  
temperature range, and automatic recharge. The device is  
specified for operation in ambient temperatures from -40°C to  
+85°C and is offered in a 3x3mm thermally enhanced DFN  
package.  
• Guaranteed to operate down to 2.65V after start-up  
• Ambient temperature range: -40°C to +85°C  
AEC-Q100 qualified  
Applications  
• Automotive systems  
• eCall systems
