LMH1982SQEEVAL

Evaluation and Demonstration Boards and Kits are designed to evaluate, demonstrate, and familiarize designers with an integrated circuit in a cost-effective manner. An example of such a board is the LMH1982SQEEVAL, which is a type of MOSFET-based power driver and switch board. This article focuses on the application of the board and its working principles.

An important application of the LMH1982SQEEVAL board is the ability to use it to prototype switches and power drivers. For instance, the board is useful in prototyping efficient low-side and high-side power switches using MOSFETs. It can also be used to build and test new power-trading designs quickly. These designs can involve electronic devices in the field of power conversion, such as inverters and motor control power drives.

The board is also useful in the development and verification of complete power management projects. As the board contains two high-drive MOSFETs with integrated drivers, it can be used as a power switch for output currents up to 25A. Furthermore, it can be used as a bidirectional switcher and power distribution block for 12V to 80V supplies. This makes it suitable for applications such as automotive, telecom, and industrial systems.

Another application area in which the LMH1982SQEEVAL can be of great value is in the testing and evaluation of power integrated circuits. The board provides a platform to evaluate, simulate, and troubleshoot complex power topologies. The board also supports high current, low voltage power devices. This makes it possible to interface the MOSFETs to the IC under test with minimal parasitic influences.

In addition to its ability to use in various applications, the board is very easy to use due to its intuitive configuration. The board is fitted with two MOSFETs of N-FET and P-FET types. The FETs are connected to their respective high-drive, 1.2A gate drivers through the DrvControl and DrvEnable pins. The board is equipped with 100K load resistor between each pair of half-bridge. This allows the user to connect a load between the A and B outputs.

The LMH1982SQEEVAL board also comes with a number of other features that makes it very user-friendly. For instance, its standalone mode makes it easy to test the board without external control. Similarly, it has a functional RUN/STOP and “Remote Protect” mode that can be used to safely monitor its performance. The board also features panel LED indicators for current, temperature, and fault detection. Furthermore, it contains a voltage regulator and two LIN-interfaced communication buses as well.

In conclusion, the LMH1982SQEEVAL board is a powerful and versatile tool that can be used in a wide range of applications. It has a simplified setup that makes it easy to use for prototyping switches and power drivers. Furthermore, it comes with a number of supportive features, such as panel LED indicators, standalone mode, and voltage regulator, that enhance its usability. Therefore, the LMH1982SQEEVAL is an perfect choice for those who are looking for an economical solution for their power electronics applications.
