Why is the CAN bus terminal resistor 120Ω?
The CAN bus terminal resistance is generally 120 ohms. In fact, when designing, there are two 60 ohms resistance stringing, and there are generally two 120Ω nodes on the bus. Basically, people who know a little CAN bus are a little bit. Everyone knows this. There are three effects of the CAN bus...Read more -
Why is SiC so “divine”?
Compared with silicon-based power semiconductors, SiC (silicon carbide) power semiconductors have significant advantages in switching frequency, loss, heat dissipation, miniaturization, etc. With the large-scale production of silicon carbide inverters by Tesla, more companies have also begun to l...Read more -
What is pulling current, irrigation current, absorbing current?
Pull current and irrigation current are parameters of measuring circuit output drive capabilities (note: pulling and irrigation are all for the output end, so it is the driver capacity) parameters. This statement is generally used in digital circuits. Here we must first explain that the pull and...Read more -
