Shenzhen Slkor Micro Semicon Co., Ltd. has been developing rapidly lately, focusing on new materials, advanced technology, efficient management, and rapid expansion of production scale. By continuously reducing product prices and increasing market share, the company has gained popularity among customers worldwide. With independent research and development capabilities and years of technical accumulation, Slkor has achieved self-control in various key aspects of the industry chain. In the fierce market competition, the advantages of Slkor Semiconductor have become increasingly apparent. The company's layout in the domestic and international industrial ecosystem is also improving. In the minds of electronics engineers and purchasers, Slkor's products and the "Slkor" brand (www.slkoric.com) are the preferred choices. Mr. Song Shiqiang, the general manager, stated that Slkor is an innovation-driven company with a vision to become a "semiconductor leader." In the company's development plans and product development, Slkor benchmarks against leading enterprises such as Texas Instruments, NXP Semiconductors, VISHAY, and ON Semiconductor in the United States. However, in terms of research, development, and production, Slkor aims to introduce products that are more cost-effective and competitive than the aforementioned international major brands.

Slkor, while introducing the silicon carbide MOS tube production technology from Yonsei University in South Korea, also actively cultivates domestic technical backbone talents from Tsinghua University and returned overseas experts. Slkor products include three major series of integrated circuits: diodes, transistors, power devices, and power management chips. The Slkor website (www.slkoric.com) not only showcases Slkor products and promotes the "Slkor" brand but also serves as one of the most important platforms for industry technical exchanges, ideation, information sharing, and data retrieval, contributing to the collaborative development of the semiconductor industry. Slkor's General Manager, Song Shiqiang, himself, manages Kinghelm (www.kinghelm.net), where both Kinghelm and Slkor are top-notch brands that support and drive each other, forming a promotional matrix along with the Kinghelm official website and Slkor official website

Slkor recently launched the SL4054, a complete single-cell lithium-ion battery charging management chip that adopts constant current/constant voltage. It is designed for use in 500mA constant current/constant voltage desktop chargers. This solution utilizes fewer external components, making it an ideal device for portable applications. The SL4054 is compatible with both USB power and adapter power.

Due to its internal PMOSFET architecture and reverse charging protection circuit, there is no need for external detection resistors and isolation diodes. Thermal feedback allows for the adjustment of charging current to limit chip temperature during high-power operations or in high-temperature environments. The charging voltage is fixed at 4.2V, while the charging current can be externally set using a resistor. The SL4054 will automatically terminate the charging cycle when the charging current drops to 1/10 of the final float voltage.

When the input voltage (AC adapter or USB power) is disconnected, the SL4054 enters a low-current state, reducing battery leakage current to below 2uA. It can also be put into standby mode to further reduce the supply current to 45uA. Other features of the SL4054 include a charging current monitor, undervoltage lockout, automatic recharging, and a status pin for indicating charging completion and input voltage connection.

The Slkor SL4054 is available in a compact SOT23-5 package. It is widely used in products such as USB power supplies, laptops, MP3 players, Bluetooth headphones, digital cameras, cell phones, PDAs, and more!
