The Star*Power Radiation Hardened IS-2981RH, IS-2981EH are monolithic devices designed for use in high-side switching applications that benefit from separate grounds for the logic and loads. The devices have a 5V to 80V operating supply voltage range and is capable of sourcing -200mA continuously from each output. The outputs are controlled by active-high inputs and may be paralleled to increase the drive current. The output clamp diodes prevent device damage, when switching inductive loads. Constructed with the Intersil bonded wafer, dielectrically isolated HVTDLM process, these single event latch-up immune devices have been specifically designed to provide highly reliable performance in harsh radiation environments. They are fully guaranteed for 100krad(Si) high dose rate and 50krad(Si) low dose rate total dose performance through wafer-by-wafer radiation testing, and are production tested over the full military temperature range. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed below must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-00520.
