Lithium battery charging and discharging module based on FM5324G

Modular solution. It can be used as a patch module for SMT.

FM5324G is an integrated power management IC used in mobile power supplies that integrates lithium battery charging management, battery boost output, battery power judgment and LED power indication.

FM5324G is charged in a switching mode, including trickle charging, constant current charging and constant voltage charging. The floating charging voltage accuracy can reach ±1% in the full temperature range, and it has small charging current ripple and high charging efficiency. High advantages.

FM5324G's DC-DC boost can achieve an accuracy of ±1% and can provide a boost conversion efficiency of up to more than 94%, extending battery life.

FM5324G is equipped with 3 LED drive ports, which can drive 4 LEDs to display battery power. The chip has a built-in logic lock function to prevent the power indicator from being unstable.

FM5324G has multiple protection designs, including load overcurrent protection, soft start protection, input overvoltage protection, output short circuit protection, chip temperature protection, battery temperature protection, etc. At the same time, the chip port is designed with a high-performance ESD protection circuit, making the chip extremely reliable.
