IS-1715ARH
Radiation Hardened
Complementary Switch FET Driver
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 Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-00521. A “hot-link” is provided
on our homepage for downloading.
