Introduction
DCDC Power Delivery Diagram
Power Delivery Design
Refer to Appendix A – References for design schematics.
Configuration Parameters
Please refer to AN_448_FT4233HP_FT2233HP_FT233HP_Configuration_Guide for details.
EEPROM Settings
Based on the configuration above, and set through programming an external EEPROM using FT_PROG, an FTx233HP/FT233HP will execute power delivery from PD2 (SNK only) to PD1 (SNK/SOURCE).
GPIO Indicator
Table 1 – GPIO Indicator
| EEPROM Setting | GPIO Indicator |
|---|---|
| 9V3A | GPIO0 = GPIO1 = High |
Other GPIO pins are low
12V3A| GPIO0 = GPIO7 = High
Other GPIO pins are low
15V3A| GPIO0 = GPIO6 = High
Other GPIO pins are low
20V3A| GPIO0 = GPIO3 = High
Other GPIO pins are low
Note: Since GPIO6/7 does not exist in FTx232HP/FT232HP, user can use GPIO1-3 to configure with board design.
