Hello,To protect USB port, I recommend USBLC6-2P6 (ESD only) or ECMF2-40A100N6 (ESD + CMF) to place as close as possible to the connectors.Your issue may be not link to Vf voltage of the ESD protections when placed in parallel.I suspect an impedance ...
The EN pin determines the voltage reference for the I2C bus (either 1.8V or 3.3V) and activates the I2C functionality. It is crucial to link this pin to a GPIO that outputs the same voltage level as the I2C port.Unlike a threshold-triggered I/O, this...
Hello, TCPP protection devices (TCPP01-M12 or TCPP03-M20) handle dead battery (DB) signaling even when there's no power, making direct connections between UCPD1_DBCCx and UCPD1_CCx useless.Thus, the pins typically used for UCPD1_DBCCx can be repurpos...
Hello,Your understading is correct.Pull-up resistor on EN pin is useless. GPIO output for EN pin must be push-pull no pull-up, no pull-down resistor.Best regards,Mathieu
Hello,Spice models are not avalaible.Nevertheless, I recommend you to use STM32 with UCPD + TCPP solution.Much more flexibility, eco-system available to ease development and cost effective.See : https://www.st.com/content/st_com/en/ecosystems/stm32-u...
