描述 Description

The RT1738A is an USB Type-C interface over-voltage protection IC.



The RT1738A 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 RT1738A 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 RT1738A is available in a 3x3mm WQFN package.
