Resolved! Can anyone please send a minimum set of config parameters and digital input settings for L9945 to - switch a high-side FET on channel 1 on and off via SPI - turn a motor in one direction on bridge 1.
No matter what we try, nothing happens. For case 2, the L9945 receives the PWM.Thank you in advance. Best regads: Balázs Bámer
Wireless charging coil selection
Hello.We are trying to develop a new product that will implement wireless charging technology and we are trying to follow the guidelines noted in the Qi specification. We have our eyes set on the STWBC-EP family.There are some considerations for this...
IHM06A1 STSPIN220 stepper motor is getting maximum current and there is voltage drop while stepper motor is in rest condition.
HelloI am intern and I am trying to control stepper motor by IHM06A1 StSpin220 stepper motor using STM32F401RE. When motor is in rest mode then there is voltage drop and STSPIN220 is taking maximum current and voltage becomes half with any motor. I a...
Read actual voltages from STPMIC1
I'm reading the datasheet of STMPiC1 and I wonder if there's a way to read the actual voltages and/or currents. Not the setpoint ( = control registers) but the real voltages at one moment.
STEVAL-ISC005V1 evaluation board - not getting 15V from PDO2
I bought STEVAL-ISC005V1 evaluation board from digikey, used DA45C-J3WEU usb c type from artesyn embedded technologies.(Capable for providing 15V/3A)When i connected adapter, i got 19V from VSINK and PDO3, but i didn't get 15V from PDO2, led is not ...
Why IHM06A1driver gets voltage drop while getting power on when motor is in rest condition?
HelloI am using IHM06A1 driver with STM32F401RE to control stepper motor. I am supplying 5v and 0.300A for motor (according to motor datasheet ) using DC Power Supply and providing 3V/5V to IMH06A1 from STM32F401RE board. There is voltage drop at tim...
How to increase speed for STSW-SPIN3202 firmware package library
I have been working with the STSW-SPIN3202 library with the STEVAL-SPIN3202 and am unable to spin the Bull Running BR2804 above 8900rpm. I would like to have full speed control from 0-100% duty cycle but something is limiting the speed. Software deve...
Will LED2000 destroy itself if the LED load is removed while operating?
We have been using the LED2000 and LED2001 for years with great success. We have a new design where it is possible that the LED loading the output can be disconnected during operation. The LED would be running around 1.5A. That would result in a swit...
LED6000 use DIM as enable
Hi all,The LED6000 has a seperate EN and DIM line. I would like to use the dimming feature and also be able to disable the device. It seems I could use DIM only, and tie EN to VCC. Then, if I hold DIM low, the device should be disabled. As I use mult...
PM8805 PoE Controller Grounding
Hi,Looking at the PM8805 PoE Controller datasheet fig 7 and also AN5207 page 30 there is a 3M3 resistor from power ground to chassis ground. What it purpose, is this some form of bleed resistor to stop voltage build up? My main question though is why...
