MT7538 is a general-purpose USB Type-C interface overvoltage protection IC, which can quickly protect the CC/SBU terminal from the possible damage caused by the 3.3V~21V PD transmission voltage that may be in contact with the adjacent VBUS short circuit event. , Its protection capacity can reach up to 28V.
MT7538 also provides electrostatic protection against ESD contact discharge according to IEC61000-4-2, and the response speed of overvoltage protection reaches 70ns, which can quickly protect the chip.
