Power management

I have problems to setup a communication over I2C with my MCU and a STWLC33 on a STWLC33JRF eval board. The data sheet of the STWLC33 has errors. See details.

Chapter 8.5 says write the register value as two bytes (Low and High), but all pictures and descriptions later sends only one byte for the register value. Whats correct?If I send START ADR(WRITE) REG START ADR(READ) VALUE STOP the ADR byte is acknowl...

Your workshop, "Putting the right spin on Stepper and Brushless DC motors", in Santa Clara couple days ago was full, so I couldn't get in. But can I get the workshop materials?

Would appreciate getting copies of the briefing slides, list of HW and SW used, and installation/setup instructions. Thanks,Mike

I got an answer to my question by other means.

Are design files for B-G431B-ESC1 correct?

Hello,I've just downloaded the hardware design files for B-G431B-ESC1 board and looking at the pcb layout of the power stage I think there might be a problem with this design. The common drain pad for all high side MOSFETs is connected to a V+ plane ...

STEF01 startup issues

Hello there,I bought an STEF01 eval board STEVAL-EFUSE01 to test the IC out, as it is a very good fit for my upcoming project.I am having some issues starting the device into higher loads. It looks like the current limiter kicks in a little bit too e...

Is anyone successfully using NUCLEO-F303RE + STEVAL-IPM15B?

I have been more than a week trying to use unsuccesfully this board combination to develop some FOC solution for big brushlesss motors.

How to I sync two SPV1040 solar charger ICs connected in parallel so that both of them have the exact voltage set point?

I am using 2 SPV1040 that are controlling 1 solar panel per chip. With that said, I am using a super cap with no battery and when the super cap is discharged the two ICs work in unison to charge the Super cap to the voltage set point. Once that is co...
