The System Management Bus (SMBus) is a two-wire interface through which simple power-related chips can communicate with rest of the system. It uses I2C as its backbone. With the SMBus, a device can provide manufacturer information, tell the system what its model or part number is, save ...
Short for System Management Bus, the SMBus or sm bus controller was created by Intel in 1995 as a split from I2C. SMBus requires more strict electrical and protocol conventions and enables your computer motherboard to communicate with low-speed peripherals such as the battery on a laptop ...
TheSM Bus Controller, also known as theSMBusorSystem Management Bus, is a set of integrated circuits, orchipset, located within a personal computer. It provides a two-wire interface that allows system and power-related components to communicate with other parts of the computer. The SMBus monit...
Normally this would require the redesign of the power distribution system, but with digital power, a new voltage rail can be easily added to the power management system using the industry-standard SMBus. Adding a new rail is integrated into the monitoring, sequencing, margining, and fault ...

I2C goes by several names as Inter-Integrated Circuit, I2C, & IIC. I2C are two-wire data transfer bus. Wide variety of computers can take advantage of this bus.
The SMBus is comparable to the I2C bus but has different enhanced features such as voltage levels, clock frequency and a preference for an additional interrupt request wire. Although slower than the majority of buses, the I2C is an inexpensive architecture and is ideal for peripherals that do ...
