Hello Team, Good Morning! In one of our products, we recently encountered an issue with the STMicroelectronics part VN7E010AJ (HS Driver Failure). Configuration: VN7E010AJ HS driver output is connected to the horn.Observation:Without the horn connec...
Qi2.2 25W receiver
Hello,We see that there are Qi2.2 25W transmitters that have been certified. Is there any roadmap for Qi2.2 25W receivers?Thanks
VNH9030AQ footprint / land pattern?
Hello - I'm looking for a footprint or land pattern to use for designing a PCB around the VNH9030AQ. I'm sorry if I've overlooked it somewhere--can anyone point me in the right direction? Thank you for your time!
Spice Model of VIPERGAN65D
Hi, Does Spice Model of VIPERGAN65D available? If so from where can I download it?
Problem with in rush current to the DC Link Capacitor
In the DC Link Capacitor i am facing a problem like i am getting 260Arms as the inrush current for my motor controller. Although my overall operating current is 160Arms maximum. Suggest me some methods to reduce this consition.
Resolved! powerSTEP01 advanced current control parameters
Hello,are there any example parameters available to drive a stepper motor fast in current mode? I am using the EVLPOWERSTEP01 evaluation board with different stepper motors, e.g. Oriental PK267JDA (3.4V, 2.8A, 1.2Ohm) and Nanotec ST6018K2008 (4.8V, 2...
LD1117 Input & Output Capacitor requirements
I am currently designing a circuit using the LD1117S50CTR.In the recommended circuit in the datasheet, Cin = 100 nF and Cout = 10 µF are specified.For an LDO, I believe Cout is critical, while Cin is not as important.Therefore, I am considering using...
Example Code for VNF1048F
Hello ST Community, i have problems to get the VNF1048F chip to run. It goes every time to the fault state and can not find out, why this problem occurs.The documentation for this chip is not really good and there is not sample application (Source Co...
L4946A gives good PFC in discontinuous mode?
Hi,We wish to do a Boost PFC with L4986A and a 30uH inductor.Power is 2200W and Mains is 85-265VAC.When the mains is at 240VAC, the inductor current would be discontinuous for some 80% of the mains half cycle.Is this OK?Will the L4986A be able to c...
VNF1048F & VNF1248F SPI Communication without VS
Hello, We are developing a design around VNF1048F & VNF1248F products. We are considering a multichannel design with different output settings. In a multichannel design, naturally we are expecting to have control and monitoring capability of individ...
