I need a normally ON power switch. High-ish voltage (200V) and current (50A total with parallel devices), and low ON resistance are main requirements. Seems that only IXYS makes any depletion mode power MOSFETs and they are very pricey. I understand GaN devices are inherently normally ON, but it appears the GaN parts from TI and others are using a cascode FET on all their devices to make them function as normally OFF devices for use in the typical power switching circuit. But, the datasheets don't exactly call this out, nor do the search tools and I got tired of looking. Does TI have any parts that meet this requirement or any plans for any? Or, do you know of any others besides IXYS?
