CN3763 4A SSOP-10-150mil Three-section Lithium Battery Charging Management Integrated Circuit

CN3763 is a PWM-based buck-mode three-cell lithium battery charging management integrated circuit. It independently manages the charging of the three cells of lithium batteries, featuring a small package size, few peripheral components, and simple usage. CN3763 has trickle, constant current, and constant voltage charging modes, making it highly suitable for lithium battery charging management. In the constant voltage charging mode, CN3763 regulates the battery voltage to 12.6V, and it can also be adjusted upward through an external resistor; in the constant current charging mode, the charging current is set through an external resistor. For deeply discharged lithium batteries, when the battery voltage is lower than 66.5% of the constant voltage charging voltage (typical value), CN3763 performs trickle charging with 17.5% of the set constant current charge current on the battery. In the constant voltage charging stage, the charging current gradually decreases, and when the charging current drops to 16% of the constant current charging current, the charging is completed. In the charging completion state, if the battery voltage drops to 95.5% of the constant voltage charging voltage, a new charging cycle is automatically initiated. When the input power supply is lost or the input voltage is lower than the battery voltage, CN3763 automatically enters sleep mode. Other functions include input low voltage latch, battery end overvoltage protection, and charging status indication, etc. CN3763 is packaged in a 10-pin SSOP package.
