The Radiation Hardened IS- 1715ARH is a high speed, high current complementary power FET driver designed for use in synchronous rectification circuits. Soft switching transitions for the two output waveforms may be managed by setting the independently programmable delays. The delay pins can alternatively be configured for zero-voltage sensing to allow for precise switching control.

The IS-1715ARH has a single input, which is PWM and TTL compatible, 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 under voltage lock-out (UVLO) function is set at 9V(max).

Constructed with the Intersil dielectrically isolated Rad Hard Silicon Gate (RSG) process, these devices are immune to single event latch-up (SEL) and have been specifically designed to provide highly reliable performance in harsh radiation environments.

Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering.

Detailed Electrical Specifications for these devices are contained in SMD 5962-00521.
