Charger Protocol ICs

The LP103S from LOWPOWER is a high-performance fast charging interface physical layer IC, which monitors USB D+/D- data lines and automatically adjusts power supply output voltage to optimize charging efficiency. This chip features an input voltage range of V_Input 3.1V to 6.3V and ultra-low power consumption below 1mW@5V, supporting mainstream fast charging protocols and output voltages of 5V, 9V, 12V and 20V. As a UK-based distributor, ABL Semi provides 100% original LP103S components with flexible MOQ, pin-to-pin replacement support and complete compliant trade documents for global buyers.

The LP6400 from LOWPOWER is an 18W fast charge synchronous buck regulator built for high-voltage charging solutions. It supports an input voltage range of 8V to 32V and delivers a continuous 3.6A output current at 5V, compatible with QC2.0/3.0, Huawei FCP, Samsung AFC and other mainstream fast charging protocols. With low on-resistance internal MOSFETs and multiple protection functions, this SOP-8 IC greatly cuts down the use of external components. As a UK-based distributor, ABL Semi provides 100% original LP6400 with flexible MOQ and reliable pin-to-pin replacement services.
