Lithium battery charger with overvoltage protection and temperature protection function, lithium battery charger external limiting current charging power supply and P channel field-effect tube, can fast charge safe and effective for single lithium battery, its biggest feature is that it can still achieve very low power dissipation without using inductors, by 8 feet. MAX package. The charge control accuracy of 0.75%, can achieve the pre charging, the longest charging time limit for lithium battery provides two protection, lithium battery charger charging mode can make the charge to the maximum capacity of the battery.
The lithium battery charger can automatically detect the charging power supply and automatically switch off when no power is in order to reduce the leakage of the battery. Quick start filling after open the external P FET, when the detected battery voltage reaches the preset threshold into the pulse charging mode, P channel field-effect tube open will be a shorter period of time, at the end of charge, LED indicator light will be blinking at the 12% cycle. When the power supply and battery charging within the normal working temperature range, insert the battery will start a charging process; the end of charging condition is pulse charging current to achieve the fast charge current average of 1%, or longer than the charging time on the preset.
