Bi-Directional Controller IC Employs Supercapacitors For DC Power Backup

Power outages lasting just a few seconds can impact a system’s operating functions and also cause a loss of important data. In the past, a UPS (uninterruptible power supply) might have been used as a power backup, but it is overkill for short duration outages and requires constant attention to its batteries. Now, there is Linear Technology’s LTC3350, a mixed-signal

IGBTs: Frequently Asked Questions

The IGBT combines the simple gate-drive characteristics of the MOSFET with the high-current and low-saturation-voltage capability of the bipolar transistor in a single device. What is an IGBT? The insulated-gate bipolar transistor (IGBT) is essentially a three-terminal power semiconductor device typically used as an electronic switch in a wide range of applications. The IGBT combines the simple gate-drive characteristics of
