Lithium battery charge management integrated circuit

Lithium Battery Charging Management IC:

AP5056 is a complete single-cell lithium-ion battery using a constant current/constant voltage linear charger. Its SOP8 package with bottom heat sink and low external component count make the AP5056 ideal for portable applications. AP5056 can work with USB power supply and adapter power supply.

Due to the internal PMOSFET structure and anti-reverse charge circuit, no external isolation diode is required. Thermal feedback automatically adjusts the load current to limit chip temperature during high-power operation or high ambient temperature conditions. The charging voltage is fixed at 4.2 V, while the charging current can be adjusted externally via a resistor. When the charging current drops to 1/10 of the set value after reaching the final float voltage, the AP5056 switchesautomatically ends the charge cycle.

When the input voltage (AC adapter or USB power supply) is removed, the AP5056 automatically enters a low current state, reducing the battery leakage current to less than 2uA. The AP5056 can also be placed in shutdown mode when power is available, reducing the supply current to 50 µA.

Other features of the AP5056 include battery temperature detection, undervoltage lockout, auto-recharge, and two LED status pins to indicate when charging is complete .

Please recommend 5V boost lithium battery charging IC

I think you are looking for a lithium battery protection IC manufacturer.

Front-line manufacturers include Japan's Seiko and Liguang, as well as Taiwan's Hongkang HYCON and Fujing.

The second level includes the Fuman, BYD Micro, Zhongying, etc. locally produced.

Personally, I recommend products made in Taiwan, which are more cost-effective. If you only want low-end products, you can choose domestic products.

We are specialized in this type of protection IC.

S4059D four-cell lithium battery booster charging IC

Overview

FS4059D is a 5V input, supporting the integrated circuit of four-cell lithium battery boost charge management.

The FS4059D has a built-in MOS transistor and adopts an asynchronous switching architecture, which requires very few peripherals during application, which can effectively reduce the overall size of the solution and the cost of the bill of materials. .
