L6599 LLC resonant converter start up issue

Apply 15V at Vcc pinApply 50V at top of potential divider formed by 6M6 and 180k ohm at LINE pin in order to get LINE pin voltage >1.23VHowever, High side LLC mosfet (connected to HVG pin, on resistance: 47ohm, off resistance 10ohm) GS...

Can I use the SPINFamily Evaluation Tool to develop and test Python software for use on another platform? (Linux)

I'd like to use the STSW-SPIN002 SPINFamily Evaluation Tool to develop a python application for controlling the L6470, and then move it to my final hardware environment (ARM Linux) for final debug and deployment once the hardware is ready. However ...

Feed error on the STEVAL-CTM009V1 board

The supply of the STEVAL-CTM009V1 board is shown to be up to 48 V. However, the A7986ATR writes that the A6902D13TR buck converter has a maximum supply of 38V.How does this board work at 48V?Or is the feeding range of the board written wrong?

How to change the motor parameters (ex: poles, rs, ls) without MotorControl Workbench?

I have a motor driver board (brush-less) and want to the board can run different motor through the UART. is there a way can do it? I don't want to recompile every time I change parameters.

Page 44 of the L6360 datasheet states that "The linear regulator minimum limitation current value is ILIMLR." However, ILIMLR is not defined in the datasheet. Can you please provide the value of ILIMLR?

How to turn off and on wireless charging using host through uart interface for stwbc-ep digital wireless charging controller ?

We are interfaced stwbc-ep with host microcontroller using uart. we want the feature to turn off charging,turn on charging based on some events. We have gone through the user manual of firmware given by st. but didn't found any register to turn off o...

Can I control the current limit of VNQ5027AK HSD?

General question on motor code organization

Hi All,I am using the FOC code on a STM302x device and I plan on adding an outer loop to control the motor phase relative to a frequency reference. I've been advised by an ST Apps Mgr not to modify the FOC code library, which I fully agree with. The ...

How to use SRK2001A with bridge circuit

Hello everybody,I'm working on a power supply with a LLC resonant converter without centertap in it.For the secondary side rectification I want to use a SRK2001A but i don't know how to use SRK2001A with bridge circuit.Is it possible to place SVS1 an...

we use the triac BTA/BTB16 for 1 Phase Control of a Feeder ( 230 VAC, 50 Hz). attached the LTspice- Simulation. Question: why is the current not symetric ? Bernd
