Procurement Notes

Verify that the specific order matches the TCPP02-M18 part number to ensure compatibility with STM32 microcontrollers featuring UCPD peripherals. Confirm that the application design accounts for the required external N-channel MOSFET and associated passive components. Ensure the PCB layout supports the specified thermal dissipation for the operating temperature range. Check for any specific ordering suffixes if available in official documentation, as they may indicate package variations or tape/reel configurations.

Selection Notes

Select this component when designing a cost-effective USB-C source solution requiring compliance with PD 3.1 and PPS specifications. It is suitable for applications needing integrated protection for VBUS and CC lines without complex external circuitry. Consider its dual I2C address capability if designing multi-port systems. Ensure the host MCU can interface with the analog current sense output and manage the gate driver signals effectively.
