The rising edge of the on-chip oscillator turns on the output. Turn-off is controlled by the current sense comparator and occurs when the sensed current reaches a peak controlled by the error amplifier. Constructed with Intersil’s Rad Hard Silicon Gate (RSG) dielectrically isolated BiCMOS process, these devices are immune to single event latch-up and have been specifically designed to provide a high level of immunity to single event transients. All specified parameters are guaranteed and tested for 300krad(Si) total dose performance at a high dose rate and 50krad(Si) total dose at a low dose rate. Detailed Electrical Specifications for these devices are contained in the SMD 5962-01509. A “hot-link” is also prov...
