Spice Model for STW15NK

Hi,I tried to use the spice model for the STW15NK (.subckt) but it dosn't work with LTspice.I imported the .subckt with LTspice without any error.But the FET don't torn on/off with the input signal on Gate.Any known issues?thanks,Martin

VNH5019A-E gets damaged while hot plugging with motor, as we disconnect the motor when it is being driven by this H-bridge. Kindly find attached schematic. We require your valuable feedback in this regards. Thank you very much.

We are using VNH5019A-E to drive an actuator. We have followed all the schematic mentioned in evaluation board of VNH5019A-E for the system. We have a case when we have to disconnect the motor while this H-bridge IC is driving it. In this scenario of...

i want to send 8 to 35v @16A through the mosfet. so can i use this mosfet (VND5025AKTR-E) for the abow voltage and current ratings? i want to know VND5025AKTR-E continuous current flow.

STSPIN240 - never get fault interrupt

I'm driving a small engine and almost everything works well. Running current is about 13mA and 80mA at the end when it is directly driven. When driving with the STSPIN240 and the actuator come to an end the driver's output go into switch mode and lim...

Using L6924 based charging station with UL approved wall adapter, does the charging station need UL approval too?

Using L6924 based charging station with UL approved wall adapter, does the charging station need UL approval too, what other regulatory testing is required on the charging station.

We need to find an IC which can monitor 12 v 7 mAH SMF battery. Which IC is most suitable?

Does anyone know where to find recommended footprints for STM products?

I'm looking for footprint recommendations for VNH7100AS (and other ST products) and I can't find them. https://www.st.com/content/st_com/en/products/automotive-analog-and-power/motor-driver-ics/vnh7100as.html#quality-scroll

POWERSTEP01

I am developing a control system, for an industrial doser, for this I use a stepper motor, of 5.6amp, 0.5 ohm, 3.6mh and a KE .233.I have all the system implemented, hardware and software.To tune the engine I used the EVLPOWERSTEP01 development tools...

How to reduce the zero current offset reading from one of the channel of STPM33?

Hi, I am using STPM33 for energy monitering. I have 2 STPM33 in my design and hence there are 4 current sense channels where I use shunt resistors for sensing. The problem faced by me is that the fourth channel is showing an offset of 6 mA when zero ...
