• IP = 2X IC
Peak Duration for rated IP ≈ Typical 3 seconds.Read More »
“R” Type current limits
stead of having “fuse” I2t limits to the IP, the R type has not IP capabilities, but only continuous current capabilities that is higher than the “traditional” IC (by 1.5) and is only thermally limited.Read More »
Power Switching- FASST
The FASST Technology is realized in the FID, Elmo’s fully customized analog/digital IC designed to “Optimum Drive” of power MosFETs and IGBTs
- Provides fast and highly efficient switching
- Keeps process “soft” with no stress on power device with very low EMI.
