2, TP4056

The TP4056 is a complete single-cell Li-Ion battery with a constant current/constant voltage linear charger. The SOP8 package with heatsink on the bottom and a small number of external components make the TP4056 ideal for portable applications. The TP4056 is suitable for USB power and adapter power supplies.

3, HL7016

The HL7016 is the first 12V high-voltage input fully integrated switch mode charger in China, which realizes high input voltage and USBOTG boost mode and I2C interface programmable. The chip has built-in voltage, current, temperature and other detection and protection functions. The voltage and current parameters are set and adjusted through the I2C interface to ensure the safety of lithium battery charging. In addition, the chip also has a built-in battery activation function to solve the system crash caused by battery short circuit. Compared with the traditional charging method, the HL7016 reduces the charging time by more than half.

4, CS0301

CS0301 is a high-precision intelligent battery charging management chip with full functions, low price, high integration, simple external circuit and convenient adjustment.

5, LTH7

The LTH7 (Model: PL4054) is a complete single-cell Li-Ion battery with a constant current/constant voltage linear charger. Its SOT package and fewer external components make the PL4054 an ideal choice for portable applications.

6, CH4054

The CH4054 is a single-cell Li-Ion battery constant current/constant voltage linear charger. The simple external application circuit is ideal for portable device applications. It is suitable for USB power supply and adapter power supply. It has an internal anti-reverse charging circuit and does not require an external isolation diode. Thermal feedback automatically adjusts the charge current to limit chip temperature during high power operation or high ambient temperature conditions.
