Applications

Protect both your USB data port and VBus line with one TVS device

The RClampXX54P is optimized for use on systems that utilize the USB interface for battery charging. Low capacitance protection is provided for the USB data (DM, DP) and USB ID pins. The maximum capacitance on these lines is <1pF for maximum signal integrity. All three lines are referenced to an internal 5 volt TVS device. A separate TVS device is used for protection of the USB voltage bus. This allows battery charging without signal clipping. Depending on the Vbus voltage requirements Semtech offer three different devices.
