Dec 21, 2017 Radiation Hardened Complementary Switch FET Drivers The radiation hardened IS-1715ARH and IS-1715AEH
are high speed, high current, complementary 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. Features Electrically screened to SMD #5962-00521 QML qualified per MIL-PRF-38535 requirements Radiation environment Gamma dose 3x105rad(Si) Latch-up immune The IS-1715ARH and IS-1715AEH have 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 Undervoltage Lockout
(UVLO) function is set at 9V (maximum). PWR output current (source and sink): 3A (peak) These devices are constructed with the Intersil
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. Both outputs active-low in Sleep mode AUX output current (source and sink): 3A (peak) Low operating supply current: 6mA (max) Wide programmable delay range: 100ns to 600ns Configurable for zero-voltage switching Switching frequency to 1MHz 9V (maximum) UVLO Related Literature For a full list of related documents, visit our website IS-1715ARH, IS-1715AEH product pages Applications Synchronous rectification in power supplies …
