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, 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 ...

How do I get my motor to spin?

I have a BLDC  4 poles motor with a rated voltage and current of 36V and 7A. I followed the instructions on the get started pdf for the STEVAL-SPIN3201 board, tried to change de start-up parameters and I can't get my motor to spin.

L6235 Motor jumps to Max above certain reference voltage

Posted on August 01, 2016 at 10:17Right now I am working with the evaluation board EVAL6235N and I adapted the L6235PD to it and changed the Shunts to 0,167 Ohms. The motor is a fan from Micronel which has a maximum average current of 1,5A when free...

CURRENT MEASUREMENT BY 2 SHUNT RESISTORS

Hi All,Having some doubts regarding the current sense.When using dual shunt current sensing technique, we have 2 current sense resistor at the Phase A and Phase B inverter legs.The 3rd phase current can be calculated in code.But ,my concern is regard...
