CXLB73241 is a single cell lithium iron phosphate battery charging management chip that can be powered by solar energy. The device includes power transistors internally and does not require external current sensing resistors or resistive diodes. The internal charging current adaptive module can automatically adjust the charging current according to the current output capability of the input power supply. Users do not need to consider the worst-case scenario and can maximize the use of the current output capability of the input power supply. It is very suitable for charging lithium iron phosphate batteries powered by power sources with limited current output capabilities such as solar panels. CXLB73241 requires very few peripheral components and is very suitable for portable applications. Thermal modulation circuit can control the temperature of the chip when the power consumption of the device is relatively high or the ambient temperature is relatively highmoj嘉泰姆
Around 132 ℃ to avoid excessive chip temperature. The internally fixed constant voltage charging voltage is 3.63V, which can also be adjusted upwards through an external resistor. The charging current is set through an external resistor. When the input voltage drops, CXLB73241 automatically enters low-power sleep mode, and the battery current is less than 3 microamperes. Other functions include low input voltage latch, automatic recharging, JEITA compliant battery temperature monitoring, charging current overcurrent protection, and charging status/charging end status indication. CXLB73241 adopts the heat dissipation enhanced 8-pin SOP package (eSOP8).
