The EV4501-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP4501. The MP4501 is a highly integrated USB Type-C protector that provides 60V short-to-VBUS over-voltage protection (OVP) and IEC ESD protection.
USB power delivery (PD) extended power range (EPR) mode allows the VBUS pin voltage (VBUS) to increase up to 48V. In the USB Type-C connector, the CC1/CC2 and SBU1/SBU2 pins are the neighbor pins close to the VBUS pin that may be physically shorted to VBUS for abnormal connections.
The MP4501 integrates four high-voltage switches that enhance the CC1/CC2 and SBU1/SBU2 pins with a 60V voltage tolerance. If a short-to-VBUS fault occurs, then the MP4501 triggers OVP with a fast response and quickly disconnects the connector from the system controller side.
The MP4501 is available in a TQFN-20 (3mmx3mm) package.
It is recommended to read the MP4501 datasheet prior to making any changes to the EV4501-Q-00A.
