Description

The 1SD1548AI IGBT driver is based on CONCEPT's highly approved SCALE-1 chip set that was developed specifically to enable IGBTs to be reliably-driven and safely operated. The driver features a high gate current of ±48 A and a high power output of 15 W. It has been specially developed for high-frequency applications (e.g. resonant converters) with a high gate power requirement or for high gate-current driving applications (e.g. parallel connection of high-power IGBT modules).
The driver features electrical isolation between the control electronics and the power section. The gate voltage is ±15 V.
The driver is equipped with a programmable Vce-monitoring function for protection against short circuit and overcurrent.
The integrated, electrically-insulated DC/DC converter supplies a drive power of 15 W.

Highest Reliability
SCALE-1 drivers have been established as an industrial standard since 1999, and the 1SD1548AI has been proven in numerous industrial and traction applications.
