L6470 "blows up" in certain operating mode

We are using a L6470 to drive a stepper. We use the SW-Pin to hold the motor in stop condition. The SW-pin causes a hard stop on falling edge. To prevent the motor from running again also if the firmware would send a run command we provide a clock si...

BTA41-800BRG X-Ray to show an extra die/lead holder in the middle leg.Is this situation normal？

These 5 pcs were mounted on board and test for functional and found 1 component failed then we do x-ray to see what different for good and fail component is.​This is x-ray picture of the good and fail component.  There is some excess die/lead frame a...

How much current required by the enable pin of the LDK130 / LDK120.

Actually, In our production we are replacing TI's LDO P/N: TPS71701DCKR with ST's P/N: LDK120 / LDK130. With ST part the output of the the LDO are not present even other DC-DC Regulators/LDO which shares same Enable signal, are not able to output the...

The capacitors of STEVAL-CTM005V1 and the power side MOSFETS (STH315N10F7) are the components whose Will have 48V in their pins. can I have just 12V in their pin ?

In the documentation for the STEVAL-CTM009V1 demo board there is a table where the minimum DC bus voltage is listed as 36V, is this really the minimum voltage for the power stage? Why can I not run this board using a motor supply (DC Bus) of 12V ?

I don't need the motor control board, I have my own, I just need the power stage and the capacitor board.

Trying to identify a component. It is in a T220 package used in a light dimming circuit. I suspect it is a FET but have no details of the circuit.

Markings are 130 360 GK1H2 VU CHN 833 ST Logo I have not been able to get a hit on any searches. I have even tried Google image search. I do electronic repair and have devices where this component has been blown. Attach is a photo of the m...

we are using Viper16LN to generate 12VDC and 5VDC from 230 VAC. 2 bulky capacitors 10uF 450V are used in i/p side of Viper as per AN2872 Application note. These high value capacitors height is more but we have height constraint max 10mm.

so any solution..

About the substitute of VIPerA16

Now, We are use VIPerA16 in the power supply circuit of the car. However, it is said that it cannot be supplied for new designs model. Is there a replacement?I hope AEC（Automotive Electronics Council) Standard grade.

Is it safe to operate the STCS1A LED driver with the EN (shutdown) and PWM pins tied together?

I am developing software for an existing board that includes the STCS1A 1.5 A max constant current LED driver.Our board currently uses that chip with the PWM pin set to steady on or off only, and it works fine. We have many in production.Now we are c...

STCS1PUR went flashing after connected to power. Need a solution.

I am using the same schematics as the datasheet's typical application schematics sugguests. The EN and PWM pin were tied together with Vin. When I connect it to 12V power, It went steady for a couple of seconds then it starts to flash, it turns off a...
