Description
The TCPP03-M20 is an MCU companion chip enabling cost-effective USB-C power delivery dual role power implementation. It provides protections and functionalities to safely comply with the USB-C Power Delivery specification. TCPP03-M20 drives external N-MOSFETs on VBUS connector pin in the source and sink power path for over voltage and over current protection. It provides an analog current sense output accessible for an MCU ADC, thus minimizing system cost. The TCPP03-M20 features 24 V tolerant ESD protection as per IEC61000-4-2 level 4 on USB type-C connector communication channel pins (CC). The TCPP03-M20 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. TCPP03-M20 helps to minimize power consumption during DRP toggling states thanks to its three programmable power modes allowing a power consumption as low as 3 µA maximum, up to 125 °C and thanks to enable pin that wake up the MCU.
