Ohmsemi has introduced the OM5358 series, an intelligent protocol controller designed to eliminate the annoying brief power drops during "power reallocation" in multi-port chargers. Through its "Non-Stop Power" architecture, the chip ensures that small-current devices stay powered even when other devices are plugged in.

Ohmsemi OM5358 Released: Triple-Port Fast Charging with Smart

Key Highlights of the OM5358：

● Protocol Support： Supports 65W output, PD3.2, UFCS, and mainstream fast-charging standards.

● Smart Identification： Recognizes 5V non-fast-charging or ultra-light loads (1μA) and uses an internal backup source to bypass power resets during renegotiation.

● High Integration： Built-in VBUS MOS, sensing resistors, and feedback networks reduce BOM cost and PCB complexity.

● Versatility： Available in a USB-C and 2 USB-As, 2 USB-C and a USB-A, and 3 USB-Cs layouts for desktop chargers and smart strips.

● Safety & Precision： Includes NTC thermal regulation, cable loss compensation, and full hardware protection.

Certified by USB-IF, the OM5358 represents a new generation of fast-charging tech that focuses on stable power delivery rather than just high wattage.
