Description

The TCPP02-M18 is a MCU companion chip enabling cost-effective USB-C source

solution. It provides protections and functionalities to safely comply with the USB-C

specification.

On provider path, TCPP02-M18 drives external N-channel MOSFET to ensure

overcurrent protection on VBUS pin, as well as a discharge path. It features an

analog current sense and amplifier with an output accessible for a MCU ADC, thus

minimizing system cost.

The TCPP02-M18 features 24 V tolerant ESD protection as per IEC61000-4-2 level

4 on USB Type-C™ connector communication channel pins (CC). Also, it provides

overvoltage protection on CC1 and CC2 pins when these pins are subjected to short

circuit with the VBUS pin that may happen when removing the USB Type-C™ cable

from its receptacle.

TCPP02-M18 embeds I2C slave registers with two possible addresses, ideal for

dual-port chargers or multiple port applications.
