3.6 Reference and Regulation
Table 17 lists the VBG specifications. VBG should be connected to an external bypass capacitor with a
minimum value of 0.1 μF. This pin is not intended for any other external use.
The following conditions apply: VPX=5 V; Barrier Powered Mode; Barrier Data Rate across the
Barrier=1.5 Mbps; VBG connected to 0.1 μF external cap.
