SKHI 71(R)

The SKHI 71(R) is designed as one kind of sixpack IGBT and MOSFET driver, SKHI 71(R) has some features such as:(1)CMOS-compatible input buffers at Vdd=5 V;(2)short-circuit protection by Vce-monitoring and soft-turn-off;(3)drive interlock top/bpttom;(4)signal transmission by opto-couplers;(5)supply undervoltage protection(13V);(6)error latch/output.Also it can be used in driver for IGBT modules in bridge circuits in choppers,inverter drives UPS and whelding inverters.

The absolute maximum ratings of the SKHI 71(R) can be summarized as:(1)supply voltage primary.:15,6 V;(2)input signal volt.(high) SKHI 27W:Vs+0.3 V;(3)output peak current:2 A;(4)output average current:20 mA;(5)max.switching frequency:50 kHz;(6)collector emitter voltage sense across the IGBT:900 V;(7)rate of rise and fall of voltage secondary to primary side:15 kV/us;(8)isolation test voltage input-output(2 sec.AC):2500 V;(9)minimum rating for Rgon:10;(10)minimum rating for Rgoff:10;(11)operating temperature:-40 to +85;(12)storage temperature:-40 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 71(R), please download the datasheet in www.seekic.com and www.chinaicmart.com .
