USB3346

Microchip's USB334x family of Hi-Speed USB 2.0 transceivers delivers enhanced USB functionality for the portable market with support for the latest USB-IF Battery Charging 1.2 (BC 1.2) specification. This family of devices dramatically reduces the time required for battery charging and system bill-of-material (BOM) costs by up to 60% over competitive solutions. Microchip has positioned itself as a leader in providing innovative solutions in support of the latest USB-IF Battery Charging specification. The new USB334x provides an excellent compliment to USB charging ports by enabling portable devices to negotiate up to three times the charging current compared to a standard USB port, resulting in faster battery charging. The USB334x is designed in a small footprint package and reduces the number of external components through the integration of voltage regulators and other discretes. Additionally, Microchip's complimentary and confidential USBCheck™ online design review service is available for customers who select the USB334x for their application design-in*.
