I am using the UCD90124/A, among other things, to monitor multiple voltages. Several of these are > 2. 5v so I have scaling circuits so as not to violate the 2. 5v max on the Mon inputs. My question is, do I enter the raw voltage values in Fusion for such things as over/under voltage fault/warning or do I use the scaled values Are there provisions

within Fusion to enter the scaling factors Enter the actual raw values into Fusion. You then set the "gain" and "offset" values in Fusion on the "Other Config" tab. For example, if your external voltage divider is a divide by 2 (0. 5), then you enter 0. 5 for Vout Scale Monitor on the other config tab for the subject rail. I have a question on the setting up "Vout scale monitor" and "Vout Cal monitor". I am monitoring a -5. 2V power rail with UCD90120A device. The Vin to UCD90120A is scaled down with 6. 04K and 8. 25K resistors (other end of the divider tied with +12V). How do I monitor the setting up the scale parameters on this scanario My first suggestion would be using an inverting Op amp between the negative rail and the UCD so that the monitoring input to the MON pin of the sequencer would be the Op amp output which is a positive voltage. I have the same question as the original post but I will elaborate more I have a 12v rail and a 1v rail I want to feed the 1v rail directly into the ADC and the 12v rail divided down. How do I enter in the scaling for EACH rail (no scaling on 1v rail and 1/6 scaling on the 12v rail). I only see one scale entry. Surely you dont want me to divide the 1v rail down to 1/6 as well All my thresholds will be in the noise. 2. Now click on the `Other Config` tab, and scroll down to the "Scaling" section. The "Vout Scale Monitor" is the scaling factor that will be applied to the rail you...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
