LP103S Overview
The LOWPOWER LP103S is a dedicated fast charge protocol controller designed for modern USB charging systems. This core IC continuously detects signals on USB D+ and D- lines, then intelligently regulates the output voltage of the connected power source to cut down charging time significantly. It supports a full suite of mainstream fast charging standards, making it a versatile solution for smart charging equipment across consumer electronics.
Built with comprehensive protection circuits, the LOWPOWER LP103S integrates output overvoltage protection, undervoltage protection, short-circuit protection, over-temperature protection and under-voltage lockout (UVLO) to guarantee operational stability. Offered in compact SOP-8 and SOT23-6 packages for space-constrained PCBs, the LP103S holds UL and Spreadtrum certifications and complies with RoHS and halogen-free regulations to meet global market requirements.
