CXLB73213 is a 2-cell lithium battery charging management chip. The chip uses time-sharing serial discharge and charging mode to charge the lithium battery; CXLB73213 with battery reverse connection protection, adopts constant current constant voltage linear control, only a small number of external components are required, making CXLB73213 an ideal choice for portable applications. Due to the internal PMOS structure and anti-reverse charging circuit, external detection resistor and isolation diode are not required. At the same time, the chip comes with chip thermal protection, which can automatically adjust the chip charging current under the condition of high power or high temperature, thus controlling the chip temperature; When the input voltage is removed, CXLB73213 automatically enters the low current mode; The full voltage is 4.2V, when the battery reaches 4.2V, the charging current drops
Predetermined valve CXLB73213 will automatically stop charging;
