FM5324GA charging and discharging module snowflake light base
overview
FM5324GA 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.
FM5324GA is charged in a switching mode, including trickle charging, constant current charging and constant voltage charging. The float charging voltage accuracy can reach ±1% in the full temperature range, and has small charging current ripple and high charging efficiency. High advantages.
The DC-DC boost of FM5324GA can achieve an accuracy of ±1%, and can provide a boost conversion efficiency of more than 94%, extending battery life.
FM5324GA 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.
Introduction
1. There is nothing to introduce. Look at the pictures. The upper and lower boards are connected and powered through copper pillars.
The pictures show
that I have no money to buy batteries, so the batteries will be replenished in the near future.
