Hi, I am trying to use STUSB4500QTR in a new board. In my design, the STUSB4500QTR is supplied from a USB-C power adaptor. The application intended for use of 20V supply. When connecting the adapter to USB-C port for first time, there is 20V on outpu...
I want to connect a Q7 board to a tablet via USB. The Q7 board is a power source (provider) and a USB device (UFP). What USB PD V3.0 solution is available? Something like STUSB4700 with PD 3.0 and not only for Power-Adapters would be great.
Hi,I am using the STUSB4500QTR in my design.Pin 3 (in QFN package) is defined as NC.I saw that in some design examples it is connected to ground.Is it alright to connect it to GND or it should left disconnected?Regards.
I am currently writing a driver for the STUSB4500L which has the ALERT pin (active low) connected to the MCU. An interrupt is triggered on a falling edge, and I then read the ALERT_STATUS_1 register. But somehow, the interrupt is not cleared. I then ...
Hi,I'm looking for USB type C PD controller IC.We need 3 USB type C ports in our design. 1st port should support dedicated power in (up to 140W) and the 2nd and 3rd port should be dedicated for power out (65W) with variable power outThe product oper...
The USB PD status register is a combination of 4 registers.The question is when read, are they interpreted as big endian or little endian?so 0x91 0x92 0x93 0x940x91 = bit 0-7, or 28 - 31?0x92 bit 8-110x93 ...0x94 ...The manual and programming guide a...
Hi,We have a custom implementation based around STM32H7 and STM32F1.The application is powered internally by a rechargable 4s li-ion battery.We use USB-PD to charge the device, and USB 2.0 to communicate with the STM32H7 through an external ULPI-PHY....
I can’t find a description of this (I_SNK_PDO_FLEX) parameter, what it is for, and what it affects in the decision-making algorithm about the power profile.Thanks.
Find a 3D model of STEVAL-CTM015V1,THANK YOU
I am using STEVAL-SPIN3202 to drive BLDC motors other than specified in the user manual - Bull-Running BR2804-1700 kV, RS Pro 57BL54 and Faulhaber Minimotor 2036U024B. No error messages observed in ST Motor pilot. But motor does not spin.Let me know ...
