SKHI 27F

The SKHI 27F is designed as one kind of hybrid dual IGBT driver, SKHI 27F has some features such as:(1)double driver for halfbridge IGBT modules;(2)SKHI 27 is compatible to old SKHI 27R;(3)SKHI 27F has additional functionality;(4)CMOS compatible inputs;(5)short circuit potection by Vce monitoring and switch off ;(6)drive interlock top/bottom;(7)isolation by transformers;(8)supply undervoltage protection(<13 V);(9)error latch/output;(10)DC bus voltage up to 1200 V.Also it can be used in (1)driver for IGBT modules in bridge circuits in choppers,inverter drives UPS and whelding inverters and (2)DC bus voltage up to 1200 V.

The absolute maximum ratings of the SKHI 27F can be summarized as:(1)supply voltage prim.:18 V;(2)input signal volt.(high) SKHI 26F:Vs+0.3 V;(3)SKHI 22B:Vs+0.3 V;(4)output peak current:+/-30 A;(5)output average current:+/-150 mA;(6)max.switching frequency:10 kHz;(7)collector emitter voltage sense across the IGBT:1700 V;(8)rate of rise and fall of voltage secondary to primary side:75 kV/us;(9)isolation test voltage input-output(2 sec.AC):4000 V;(10)minimum rating for Rgon:1.5;(11)minimum rating for Rgoff:1.5;(12)operating temperature:-25 to +85;(13)storage temperature:-25 to +85.This technical information specifies semiconductor devices but promises no characteristics.No warranty or guarantee expressed or implied is made regarding delivery,performance or suitability.If you want to know more information about SKHI 27F, please download the datasheet in www.seekic.com and www.chinaicmart.com .
