The RT1738 is an USB Type-C interface over-voltage
protection IC.
The RT1738 protects the high voltage shorted to VBUS
to adjacent pins of CC/SBU up to 28V due to USB
Power Delivery (PD) allowing VBUS from 3.3 to 21V
sourcing.
The RT1738 is integrated the protection ESDs of
IEC61000-4-2 with contact discharge ±8kV on
CON_CC1/CON_CC2, D1/D2 and ±6kV on
CON_SBU1/CON_SBU2. The surge immunity level of
CON_CC1 /CON_CC2 is up to ±35V. Besides, the
ultra-fast OVP response time of 60ns can protect the
system side of application IC from damage.
The RT1738 is available in a 3×3mm WQFN package.资料下载
