CXLB74210 is an integrated power management IC specially designed for mobile power supply, which integrates lithium battery charging management, high-efficiency boost output, LED light indication and key function module. The CXLB74210 is charged in a linear manner, which integrates the charging methods including trickle charging, constant current charging and constant voltage charging. The floating voltage accuracy can reach ± 1% in the whole temperature range, and has the advantages of small ripple of charging current and stable output voltage. The CXLB74210 DC-DC synchronous boost module integrates an internal power MOS tube, provides an output of 5V/500mA, can provide a boost conversion efficiency of up to 90%, and the output voltage can reach an accuracy of 1%. The CXLB74210 has multiple protection design, including load overcurrent protection, input overvoltage protection, output current limiting protection, output short circuit protection, chip over temperature protection. At the same time, a high-performance ESD protection circuit is designed at the chip port, which makes the chip have extremely high reliability. The CXLB74210 is equipped with an automatic load identification function, and the boost output is automatically turned on when the load is detected.
