18 / 28 page Copyright © Future Technology Devices International Limited 18 FT602Q IC Datasheet Version 1.4 Document No.: FT001389 Clearance No.: FTDI#519 6 USB Power Configurations The following sections illustrate possible USB power configurations for the FT602. The illustrations have omitted pin numbers for ease of understanding. 6.1 USB Bus-Powered Configuration Note: The reference designs here are for USB 3.1 Standard B or Micro-B connectors. Figure 6.1 Bus-Powered Configuration-1.8V/2.5V I/O Figure 6.1 illustrate the FT602 in a typical USB bus powered design configuration. The FT602 device gets its power(VCC33) from the USB bus via an external LDO(LDO_3V3) stepping the voltage down to +3.3V. Another external LDO stepping the voltage down to +2.5V for supplying the VCCIO power, connect VCCIO pins to same LDO(LDO_3V3) if VCCIO is configured to 3.3V. A ferrite bead is connected in series with the USB power supply to reduce EMI noise from the FT602 and associated circuitry being radiated down the USB cable to the USB host. The value of the Ferrite Bead depends on the total current drawn by the application. |
