Can I use HVLED001A with a resistive load up to 250W;

Can I use HVLED001A with a resistive load up to 250W;The load is up to 6A or 9A, 20V to 28V and must be below 50V. The waveform could have a a lot of rectified mains ripple because it is a simple steel wire heating element so I am considering using m...

why do I see unexpected behavior with Steval-ihm023v3?

Hello,I am using the driver Steval-ihm023v3 to run a PMSM. Previously, I used one of the TI low voltage drivers and ran my motor. Now I am using the low voltage configuration of the Steval-ihm023v3, namely "35V only", but I see weird behavior when I...

Hi, If I understand correctly, there is a solution for a FOC with Hall elements. Is there a documentation / description of how this algorithm works? Thank you very much.

How to select the Current rating of MosFET for Motor control applications?

Obviously , the surge current need to be consider prior to finalise rating of MosFET. Apart from surge current is there any thumb rule to be followed?More over, the installed current capacity of a MosFET on most of the projects are too far than the r...

Steval-esc001v1 over-current protection(OCP)

I bought a Steval-esc001v1 board and use the FW built in version 5.4.1. Everytime i boot the board,it always showed the over-current flag.Even i don't connect the motor，change HW or FW. The program exactly triggered the TIM1 BRK2 interrupt.But i foun...

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...
