Isolated Igbt Gate Driver

An isolated driver the adum4137 solves the problem of high side gate drive by means of galvanic isolation.

Isolated igbt gate driver.

Robust strong and precise single and dual channel isolated gate driver ics for mosfets igbts igbt modules sic mosfets and gan hemts eicedriver galvanically isolated gate drivers use the magnetically coupled coreless transformer ct technology to provide signal transfer across the galvanic isolation. Stgap isolated gate drivers are extremely flexible as they provide a large number of parameters that can be adjusted to best match the selected mosfet or igbt and system requirements. Electrical isolation between the input interface and the high power switching circuitry allows the device to level shift the input signals in accordance with the changing potential of the high side source or emitter node. Isolated gate drivers enable low voltage microcontrollers to safely switch high voltage power transistors on and off.

They also provide extensive diagnostic features to help enhance system robustness and reliability. The gate is the electrically isolated control terminal for each device. An igbt power mosfet is a voltage controlled device that is used as a switching element in power supply circuits and motor drives amongst other systems. The other terminals of a mosfet are source and drain and for an igbt they are called collector and emitter.

From basic and functional isolation to reinforced isolation our isolated gate drivers allow you to create designs that protect from electrical shock while providing more protection for high voltage levels.
