The USB3751A-2-A4-TR is a USB 2.0 Protection IC designed to provide over-voltage protection for internal circuits, safeguarding against VBUS levels up to 9V. It features integrated low RDSON FETs and includes an interrupt function to indicate over-voltage or under-voltage lockout conditions. The device offers robust ESD protection, rated at ±15kV for both air and contact discharge, compliant with IEC 61000-4-2 level 4 standards. This IC supports USB Battery Charger Detection for various charging port types, including Dedicated Charging Ports (DCP), Charging Downstream Ports (CDP), and Standard Downstream Ports (SDP). It also incorporates Microchip's RapidCharge Anywhere,Ñ¢ technology, allowing for charging currents up to 1.5A, significantly enhancing charging efficiency compared to traditional solutions. The USB3751A-2-A4-TR operates within an industrial temperature range of -40°C to +85°C and is housed in a compact 16-pin QFN package, measuring 3.0 mm x 3.0 mm x 0.9 mm. This product is suitable for applications requiring reliable USB connectivity and power management in battery-powered devices.
