Datasheet IS-1715ARH, IS-1715AEH 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. 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). 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.

Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed must be used when ordering. 2. These Pb-free Hermetic packaged products employ 100% Au plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. 3. The /PROTO and /SAMPLE are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity. These parts are intended for engineering evaluation purposes only. The /PROTO parts meet the electrical limits and conditions across the temperature range specified in the DLA SMD and are in the same form and fit as the qualified device. The /SAMPLE die is capable of meeting the electrical limits and conditions specified in the DLA SMD at +25°C only. The /SAMPLE is a die and does not receive 100% screening across the temperature range to the DLA SMD electrical limits. These part types do not come with a certificate of conformance because there is no radiation assurance testing and they are not DLA qualified devices. 1.3 Pin Configuration IS-1715ARH, IS-1715AEH Flatpack (CDFP4-F16) Top View NC VCC PWR VSS VSS AUX NC NC 1 16 2 15 3 14 4 13 5 12 6 11 7 10 89 ENBL T1 INPUT VSS VSS T2 VCC NC 1.4 Pin Description Pin Number 1, 7, 8, 9 2, 10 3 4, 5, 12,13 6 11 Pin Name NC VCC PWR VSS AUX T2 Description No connection.
