What is the National Instruments SMBus Controller Windows driver?

The National Instruments SMBus Controller driver is typically used for hardware components developed by National Instruments (NI) that interact with the System Management Bus (SMBus), a communication protocol primarily used for managing low-level system functions like power management, thermal monitoring, and component status in a computer system.

National Instruments (NI) manufactures hardware and software tools primarily used in engineering, industrial, and scientific applications. The SMBus Controller is part of the communication infrastructure that allows National Instruments hardware devices to communicate with the system or with other hardware components (such as sensors, batteries, and voltage regulators).
