Resolved! STPM3x INT1/2 outputs - how to configure

hi,I am now familiar with the STPM3x programming, by using EVALSTPM33/34 boards.I have been able to do some basic low voltage testing where I receive interrupts on INT1 line on EVALSTPM33/4 for voltage swell before I try mains voltages.Then I run the...

Resolved! Use of powerSTEP01 in “voltage mode�?

We are developing an OEM board which is capable of driving bipolar stepper motors from 15 to 80Vdc 10A max, in voltage mode and current control. Our customers should be able to change the supply voltage (Vbus), operating mode (voltage or current), wi...

L4985

In my 750W PFC project, I've employed the L4985A PFC controller IC. I utilized the e-design suite offered by ST to design my PFC, and I fabricated the PCB using the components specified in the e-design file. Despite ensuring that all the necessary v...

Resolved! LDL212 undervoltage mode

Hi, can you tell me what happens to the LDL212 when the input voltage drops below the output voltage+dropout? Does it track the input voltage (minus the dropout voltage)? Or does it drop out? Also, in the datasheet it mentions undervoltage lockout in...

Steval-L99615C Request Refund

I have tried every possible option to get the discovery kit working. I am not satisfied with your technical support. How do I return item for a refund?

L6470 eval board X-NUCLEO-IHM02A1 give error thermal shutdown and warning status

Hi All,I have been stuck for a week with this.7I can read and write to the registers of both L6470 correctly.And I can also send commands properly to L6470 via the SPI from STM32F407 discovery kit.However, when I try to start driving the motor, the m...

Why my STGIPS10C60-H has no output voltage

When using the chip GIPS30C60-H, sometimes the three-phase bridge switching signal is given but there is no output, regardless of whether the SD/OD pin is set high or not. This chip is used in a motor controller with a 0-270V DC bus supply and input ...
