Product Summary
The SKHI22AH4R is a hybrid dual MOSFET driver. Its typical applications are driver for MOSFET modules in bridge circuits in choppers, inverter drives, UPS and whelding inverters.
Parametrics
Absolute maximum ratings: (1)supply voltage prim, VS: 18V; (2)input signal voltage, Vih: VS+0.3V; (3)output peak current, IOUTPEAK: 40mA; (4)output average current, IOUTAVmax: 50kHz; (5)collector emitter voltage sense across the IGBT, VCEL: 1200V; (6)rate of rise and fall of voltage seconary, dv/dt: 50kV/μ.
Features
Features: (1)drives MOSFETs with VDS(on)<10V; (2)is compatible to old SKHI 21; (3)CMOS compatible inputs; (4)short circuit potection by VCE monitoring and switch off; (5)drive interlock top/bottom; (6)isolation by transformers; (7)supply undervotage protection (13V); (8)error latch/ output.
