CONN The USB-PD Middleware stack,coming from the STM32CubeG0 package, runs over the STM32G071KBU6N. This has been certified as PD Controller (TID: 5444). On the primary side, the STCH03 controller combines a high performance low-voltage PWM controller chip with a 650 V HV start-up cell in the same package, ensuring low pin count. It can operate in different modes, QR active mode, valley skipping mode and burst mode, to guarantee high efficiency at different input voltage and output load conditions. On the secondary side, the STM32G0 provides additional integration value, thanks to the embedded UCPD interface which manages the USB Type-C connector and the Power Delivery communication protocol, while controlling the adaptive synchronous rectification through its versatile peripherals and feature set. The companion TCPP01-M2 safely interfaces the USB-C connector to the MCU, ensuring the highest robustness and protecting against any destructive electrostatic discharge (ESD). It features 22 V tolerant ESD protection as per IEC61000-4-2 level 4 on USB type-C connector configuration channel (CC) pins. The ESDA15P60 ensures ESD protection higher than 30 kV on the V .
