IPM thermal issue

Hi ST experts,Would like to check if we are doing the testing of thermal rise on the STGIPQ8C60T, what will be the maximum temperature of the device can be sustained? Does it refer to the Tc in the datasheet~ 100degC?What is the pin of the device for...

I make a board with a L6235PD driver. On a population of 5 controllers, 3 have a problem.... Means that when the Vref is @0V, the motor still running (at low speed, but still running).

 I've certainly a problem with the RC OFF and RC Pulse definition....On RC pulse: 82k / 22nFOn RC OFF: 91k/470pFDo you have an idea to solve my problem??? Thanks for your help.

What's the replacement transistor for STP7NK40ZFP in DPAK package ? It's no longer manufactured.

PWD13F60 failing on dev board, shorted FETs

Hello,We are creating a design using the PWD13F60 and have done some testing with the EVALPWD13F60. We are running the gate driver portion at 12VDC, and the motor voltage up to 200VDC, but starting with lower voltages like 24, then 48, etc. We are ru...

Do I need to use a Freq to Voltage converter for a tacho signal from 4 wire fan?

Hi all,I am using a 4-wire fan supplied by 24V. I was wondering if the tacho output from the fan needs an external timer or a Freq to voltage converter; or can I just use a pull up resistor and connect the tacho signal straight to the input of STM32 ...

I have a problem with the L6498D driver, the high-side does not work

design a driver for full h-bridge using two L6498D, when i activate the LIN input the LVG output is activated and manages to turn on the low side MOSFET, but when i activate the HIN input i get a strange output of 9.6v on HVG and i am using 12v at VC...

Can't Update WS2812B LEDs After Initial

Hello,I managed to light up WS2812B LEDs by using PWM-DMA. It working well when I set up LEDs before running the code. But when I try to on/off by button it doesn't make any change. Also if I create a function like rainbow loop or basically setting a...
