STMicroelectronics TCPP01-M12 USB Type-C Port Protection

STMicroelectronics TCPP01-M12 USB Type-C Port Protection

STMicroelectronics TCPP01-M12 USB Type-C Port Protection is a single-chip solution that facilitates the migration from USB legacy connectors type-A or type-B to USB Type-C connectors. This Type-C port protection features overvoltage protection on VBUS, adjustable up to 22 V, with external N-channel MOSFET. The TCPP01-M12 USB port protection includes an integrated charge pump to control the gate of an external N-channel MOSFET. This Type-C port protection offers Over Temperature Protection (OTP), open-drain fault reporting, and integrated dead battery.

The TCPP01-M12 USB port protection operates at -40°C to 85°C junction temperature range. This Type-C port protection function with 6V overvoltage protection, 150°C junction-to-ambient thermal resistance, and 122μA supply current. The TCPP01-M12 USB Type-C port protection is ideal for use in sink configuration, source configuration, UFP or DFP configuratioN, power delivery, and PPS compliant.
