Power Distribution Controllers
ISL6115, ISL6116, ISL6117,
ISL6120
This family of fully featured hot swap power controllers
targets applications in the +2.5V to +12V range. The
ISL6115 is for +12V control, the ISL6116 for +5V, the
ISL6117 for +3.3V and the ISL6120 for +2.5V control
applications. Each has a hard wired undervoltage (UV)
monitoring and reporting threshold level approximately
80% of the aforementioned voltage.
The ISL6115 has an integrated charge pump allowing
control of up to +16V rails using an external N-Channel
MOSFET whereas the other devices utilize the +12V
bias voltage to fully enhance the N-Channel pass FET.
All ICs feature programmable overcurrent (OC)
detection, current regulation (CR) with time delay to
latch-off and soft-start.
The current regulation level is set by 2 external
resistors; R

It provides a comprehensive teaching solution for engaging students in hands-on labs involving analog circuits, mechatronics, power electronics, instrumentation, digital communications, digital electronics, controls, and more. Each laboratory solution includes lab material and complete experiments developed by experts in industry and education, so students can explore theory in the physical laboratory with a safe, in-depth experience. With its hands-on approach, NI ELVIS helps educators teach students practical, experimental engineering skills. Built on the concept of teamwork, this solution connects students to their experiments, which enables them to collaborate using the same technology in over 35,000 companies worldwide. It combines the precision and accuracy of seven benchtop instruments with the speed and customization of industrial embedded controllers in one single platform. Students can use its easy, prebuilt interfaces to customize at a level not available in any other educational laboratory equipment. Page 3 | | NI ELVIS Table 1. NI offers three NI ELVIS models.

Detailed View of NI ELVIS III Page 4 | | NI ELVIS Key Features Teach Innovation by Integrating Instrumentation with Embedded Design Projects that inherently challenge students to use innovative design thinking often involve interacting with an unknown process or device. Students are encouraged to understand the unknown through theory, simulation, and experimentation; however, projects that introduce the unknown in messy, multisystem environments tend to challenge the students to be much more innovative. Designing a test in this style requires not only knowledge of the specifications, equipment limitations, and fundamental concepts being applied but also the ability to contend with outside factors and grasp how one change can have a cascading effect on the experimental setup. Figure 1. NI ELVIS III To most effectively analyze concepts this way, students need the ability to not only instrument and analyze the experiment but also precisely control and manipulate the type and behavior of the inputs to the system. NI ELVIS III is the only engineering laboratory solution that combines seven traditional instruments with fully customizable I/O to enable the complete implementation of the concepts in this approach. Page 5 | | NI ELVIS Engage Students with a Modern, Web-Driven Experience NI ELVIS meets students where they are with a web interface that drives collaboration, reduces time to measurement, and integrates with teaching and learning resources to fully equip students in their educational careers. The seven instruments on NI ELVIS III are all accessed through a minimal installation for both Windows and Mac. This gives all students access to the instruments on their own computers instantly via USB, Ethernet, or Wi-Fi. The Bode Analyzer and the IV Analyzer are immediately accessible using a web soft front panel. This means that students can access the instruments on any device, computer, tablet, or cell phone without installing them. Only these two instruments are accessible via the web; however, every instrument will have an associated web soft front panel by the end of 2019. Figure 2. NI ELVIS Experiment and Simulation Comparison With NI ELVIS III, educators can find resources to teach and develop labs all in one place. Using the labs created for NI ELVIS, students gain access to the lab instructions, simulations, and instrument launcher all in the same window. Then, when students complete the labs, the answers are compiled and sent in as a lab report. Moving lab resources to the web with NI ELVIS III saves time and reduces the number of programs students need to use.
