RT1737

USB-C Protection Solutions for Signal Path, CC OVP Switch, VCONN Switch, SBU OVP 1:2 Switch and USB2.0 Switch with BC12 and Charging Port Configuration

The RT1737 is a highly integrated USB-C Protection IC which includes IEC-61000-4-2 ESD protection cell for SBU/DP/DM. The RT1737 integrates high voltage protection switches for DP/DM/SBU1/SBU2/CC1/CC2 to prevent high voltage VBUS from touching the adjacent pins. The AMR of DPDM/SBU/CC OVP switches is 28V. High Voltage USB 2.0 Switches also support SDP/DCP/CDP configuration.

The RT1737 also integrates SBU 1:2 OVP Mux for specific application like debugging mode, factory mode, etc.

VCONN Switch with OVP/OCP/RVP/RCP/UVP protection is also integrated. The RPD_CC1/CC2 pins function as the Rd pin in dead-battery mode and are independent of CC1/CC2, which provides each customer system with flexibility.

The RT1737 is available in a WQFN-32L 5x5 package.
