High-Side Driver application

Hi, In one of our new application, we are using different ST make high-side power switches, to switch different loads at 12V DC (Battery Input Voltage Range : 9V to 16V DC), here is the detailsIs this architecture work switching of loads through high...

LED1202 - We're able to read and write the registers via I2C, but when we set the EN bit, it does not read back as set. All other registers are readable/writable. What are we missing for setting the EN bit?

Why would STSPIN220 drive power to the outputs at initial power-on?

 To ask this question another way, what is expected at the output pins when Vs < 1.5V during power-up?I have a design for driving a linear actuator which uses the STSPIN220. My customer has an issue related to unexpected device power off, and those...

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.
