Hello - My team and I are utilizing the TCPP02-M18 in combination with the TI TPS65987 USB-C Controller in a USB Power Provider application. Right at the moment when a transition from the nominal 5V to a higher negotiated voltage occurs the TCPP02-M...

Hello - I am working on a safety critical application using the STM32L431VC that requires the VREF+ voltage rail to be powered off of a different voltage rail than the main VDD and VDDA rail. The VDD and VDDA voltage rails are being generated by a s...

Hello - I've generated a few test projects in the ST Motor Control Workbench using the default settings and my motor's parameters. I've enabled the Hall sensing on TIM4 using PB6, PB7, and PB8. Those three pins are broken out onto J6 of the EVSPIN32G...

Hello - I'm wondering if the STSPIN32G4 can be utilized to drive a brushed motor rather than a three-phase brushless motor that it is marketed for. Alternatively, are there any chips within STMicro that are meant for brushed motors that have a combi...

This helps. Thank you, Romain!-Shane

Romain -Thank you for your answer. What is not clear to me is if VDDA is 3.3V and VREF is 0V, will that be a problem? See, for example, our circuit. The VREF is sequenced off of the power supply for VDD/VDDA. There is going to be some amount of t...

Hi Cristiana - This project is generated in ST Motor Control Workbench 5.Y.4 and STM32CubeMX 6.6.1. The Firmware Package Version is STM32 FW V1.5.0 (recommended).I still have not been able to find a solution for this behavior.-Shane

I determined that this behavior is being caused by the MX_USART1_UART_Init() function call.When UART_TX_Pin (set as GPIO_PIN_9) is kept in this structure then PB6 inherently gets pulled low via what appears to be a 4.7kΩ pull-down. void HAL_UART_Msp...

Cedric - We are trying to use the STSPIN32G4 in position control. We are getting the same 'SPEED_LOOP_FREQUENCY_HZ' issue described above. Is there a way to disable the MCU monitoring portion of this to allow for position control?Also, when will ST...

STM32L431VC - Can VREF+ be sequenced off of VDD/VDDA?

EVSPIN32G4 - Hall (H1 on PB6) is being pulled to ~2V

Can the STSPIN32G4 be used to drive a brushed motor?
