IS-1715ARH, IS-1715AEH Radiation Hardened plementary Switch FET Drivers The radiation hardened IS-1715ARH and IS-1715AEH are high speed, high current, plementary power FET drivers designed for use in synchronous rectification circuits. Soft switching transitions for the two output waveforms can be managed by setting the independently programmable delays. Alternatively, the delay pins can be configured for zero-voltage sensing to allow for precise switching control. The IS-1715ARH and IS-1715AEH have a single input, which is PWM and TTL patible, and can run at frequencies up to 1MHz. The AUX output switches immediately at the rising edge of the INPUT, but waits for the T2 delay before responding to the falling edge. A logic low on the enable pin (ENBL) places both outputs into an active-low mode, and an Undervoltage Lockout (UVLO) function is set at 9V (maximum). These devices are constructed with the dielectrically isolated Rad Hard Silicon Gate (RSG) process and are immune to Single Event Latch-Up (SEL). They have been specifically designed to provide highly reliable performance in harsh radiation environments.
