SLLSES1D December 2015 – September 2020 HD3SS3220
PRODUCTION DATA
The HD3SS3220 has two power supplies: VDD5 and VCC33. The VDD5 supply powers the internal CC controller and also provides VCONN to either CC1 or CC2. The VCC33 powers the 2:1 MUX.
The HD3SS3220 non-failsafe pins are the following: PORT, ADDR, SDA/OUT1, SCL/OUT2, INT_IN/OUT3, VCONN_FAULT_N, and DIR. If any of these non-failsafe pins are pulled-up to a supply other than VDD5, then VDD5 supply must be powered up before the VCC33 supply as depicted in Figure 7-2. If it is not possible to power up VDD5 before VCC33, then the ENn_CC pin must be held high while both supplies are ramping and then asserted low after both supplies are stable as depicted in Figure 7-3.
