These inputs are referenced to an internal 5 volt TVS protection device. When the voltage on these lines exceed 5 volts, the TVS will conduct. Pin 6 is connected to the USB voltage bus (VBus). This device will conduct when the voltage on the bus exceeds 5.5 volts. The center tab is connected to ground. The path length should also be kept as short as possible to minimize parasitic inductance. For best results, multiple micro-vias are recommended to the ground plane. Protecting USB Interfaces The RClamp0854P 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 5.5 volt TVS device is used for protection of the USB voltage bus. This allows battery charging without signal clipping. A typical example is shown in Figure 2. VBus Mini USB DM USB ID GND 1 Gnd 1 2 3 4 5 DP 12 3 GND 6 5.5V 5.5V |
