Power management

Can we remove VSS power from 8 daisy chained L6470s but keep them powered by 1 external 3.3VDC supply via the VDD pins (ref. section 1-3 of ST Micro note AN4241) w/o damaging the parts? Will the L6470's retain their parameters w/o VSS but with VDD on?

Hi, I am using STPM32 with Rogowski coil, Can I use antialiasing Filtering (Double RC pole) from Coil to IINP and IIN? Thank you

viper222 design help

as shown in pictures datasheet and e designsuite both have different pin names for the same ic viper222 can anybody help regarding this topic please.thank you

ST Micro app note AN4241 shows ways of connecting logic power on L6470's to external 3.3V & 5V supplies. For external 3.3V it shows VREG & VDD are connected. Is this correct? It seems like the internal L6470 3.3V would content with the external.

I am new to ST family. For my new project i need to use stspin32f0601 for BLDC motor drive application, and also i want to know stspin32f0601 need to program or pre loaded BLDC drive program? If need program i need some example codes for BLDC control?

Has anyone experience with current limiting of motor drive VNH7100 and L9960 with stm32L433?

Hello, I am using the stm32L433Rc and a maxon motor (9 V, initial current 11,4 A, continous current 3 A). Now I am looking for a motor drive inbetween. I am thinking of using the a) VNH7100 or b) the L9960. Has any one experience with one of these? I...

Testing VN5010AK-E, need confirmation that I got the datasheet info right.

Hello to all,I found this new IC and want to test it for a while, but don't want to fry it before that :D, so just a several questions, where I doubt that I understood the datasheet correctly. There will be no uC, so I don't need current sensing, so...

What is the controller transfer function of the the L6591? Can it be used in full bridge configuration safely?

Hello,I am working on closing the loop on a system I am designing, and I am not able to determine the transfer function of the the L6591 from any literature you have, and it is not yet supported by your edseign suite software.I was hoping you could p...

FOC+HALL UVW phase current curv problem

I use FOC+HALL and the motor reduction rate is 1:1.But the phase current(one of UVW phase) is not sine wave as figure.Is it normal? how come the U/V/W phase current curv is not sine wave?what problem cause that?Thanks

Alternative package for battery charger STBC02 except BGA

We are designing a system and We are taking Power management schematic as it is from STEVAL-MKSBOX1V1(SensorTile.box) as it is best suitable for our system .but We don't want to use BGA package and battery charger STBC02 has BGA package.so is there a...
