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...

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 ...
