Do I need optocoupler to connect Steval-IHM023V3 to the microcontroller?

Hello,I want to use Steval-ihm023v3 as my motor driver and I am using a TI microcontroller. I have two questions:Do I need to use opto-couplers to connect PWM pins of the driver to MCU?Do I need to have signal conditioning fo reading the currrent of ...

We re using an STWBC-EP transmitter/charger to charge a small battery on a wearable device. We have no room to add the ST receiver, so we need the ST sample source code to talk to our microprocessor on the receiver side. Can ST supply this? Thanks,

Does somebody know how to properly scale adc current measurement on IHM07M1 expansion board?

Does somebody know how to properly scale adc current measurement on IHM07M1 expansion board (in floating-point arithmetic)?How does formula look like? Resolution of adc is 12 bits (Right alignment)Kind regards,Janusz

I can get my L9960T Evaluation board to work!

I am currently working on a project where we would like to use the L9960T and therefore we have ordered a EVAL-L9960T board.We need to use it only as a simple H-bridge without benefiting from the SPI settings and diagnostics capabilties.I have now be...

Designing doubts with SPV1040

I need to charge LiPo battery with solar cell. I found out the SPV1040. But the datasheet doesn't provide enough details, I was unable to find any document to help me, and the eDesignSuite doesn't work. Related documents use it with L6924. Can I simp...

STM32F103 power management

Hello,I m designing a board with a STM32F103. I was wondering about capacitors value. In STM32 documentation, it's written to use 100nf per VDD PIN + one 4.7uF. On the other side, I m using a low dropout regulator :I dont' understand where to place ...

Layout Recommendation for inverting DC-DC Converter MC34063

I am using the MC34063ECD-TR to take 5V and make -12V. I'm using the schematic as recommended in the datasheet for this application (with the exception of using a 100uH inductor instead of a 90uH inductor). It is working nicely electrically - I get...

Can STEVAL_POE002V1 work as 24V source?

I bought the STEVAL_POE002v1. It works fine at 5 V. Now I want to setup a POE with 24V. Can I achieve this with that STEVAL? I would think to change the transformer and to adjust the Feedback-path and perhaps the Fsw. Can you help me with a calculati...
