Lithium batteries are an energy storage device that involves the migration of lithium ions back and forth between the positive and negative electrodes to complete the charging and discharging process. It is currently one of the most widely used batteries, widely used in fields such as portable electronic devices, electric vehicles, and energy storage systems.
When choosing a lithium-ion battery charging management IC, the following aspects need to be considered:
1. Battery parameters:
Firstly, it is necessary to select the corresponding charging management IC based on the number of sections, voltage, capacity, charging current, and other parameters of the lithium battery to be charged. Different ICs are suitable for different specifications of lithium batteries, and the selection needs to match the specifications of the lithium battery.
2. Charging rate:
The charging rate supported by the charging management IC is also an important consideration. Fast charging can lead to issues such as battery overheating and reduced lifespan, so it is necessary to choose an appropriate charging rate based on actual needs.
3. Safety protection function:
The charging management IC should have various safety protection functions such as overvoltage protection, undervoltage protection, overcurrent protection, short circuit protection, temperature protection, etc. to ensure charging safety.
4. Communication interface:
Some charging management ICs also have communication interfaces that can communicate with processors or other devices to achieve functions such as battery status monitoring and charging control.
5. Cost and Supply Chain:
Finally, it is necessary to consider cost and supply chain issues, and choose a charging management IC with reasonable cost and stable supply.
In summary, when selecting a lithium-ion battery charging management IC, it is necessary to comprehensively consider factors such as lithium-ion battery parameters, charging rate, safety protection function, communication interface, cost, and supply chain.

XYT5080E is a 5V USB adapter input, high-precision dual lithium-ion battery charging management chip. It has a set of charging management chips with 0V charging function, including trickle charging, constant current charging, constant voltage charging, automatic cut-off, automatic recharging and other complete charging cycles. 9V anti surge is specially designed inside the chip, which makes the chip application safer and more reliable. The standard floating charge voltage of the XYT5080E is 8.40V. The bottom of the XYT5080E is equipped with an ESOP8 package with a heat sink grounded. The extremely compact external devices make the XYT5080E an ideal choice for the charging application of portable dual lithium-ion batteries. XYT5080E is suitable for USB adapters or other 5V adapters, greatly reducing the cost of external accessories.
When the input voltage (USB power supply or AC adapter) is removed, XYT5080E automatically enters the low current state, reducing the battery leakage current to less than 1uA. Other features of XYT5080E include: undervoltage lockout, adaptive adapter, automatic recharging, and an LED charging status indicator pin.
XYT5080E provides ESOP8L standard package.
