Description
The HS-4080AEH is a monolithic, high frequency, medium voltage Full Bridge N-Channel FET Driver IC. The device includes a TTL-level input comparator, which can be used to facilitate the “hysteresis” and PWM modes of operation. Its HEN (High Enable) lead can force current to freewheel in the bottom two external power MOSFETs, maintaining the upper power MOSFETs off. The HS-4080AEH is well suited for use in distributed DC power supplies and DC/DC converters, since it can switch at high frequencies. This device can also drive medium voltage motors and two HS-4080AEHs can be used to drive high-performance stepper motors, since the short minimum “on-time” can provide fine micro-stepping capability. Short propagation delays maximize control loop crossover frequencies and dead times, which can be adjusted to near zero to minimize distortion, resulting in precise control of the driven load. Constructed with the Intersil dielectrically isolated radiation hardened Silicon Gate (RSG) process, this device is immune to single event latch-up and has been specifically designed to provide highly reliable performance in harsh radiation environments. Complete your design with radiation hardened MOSFETs from Intersil. Detailed Electrical Specifications for these devices are contained in SMD 5962-99617.

HS-4080AEH Commercial Equivalent and Spice Model
We do not have a model for HS-4080AEH. Is HIP4080A similar to the HS-2080AEH? From a digital perspective, they are the same. The input and output states should match. However, they are a different die design, so every spec is different and their analog performance is different. Note ...

HS-4080AEH Turn-on Delay
We suggest you use the commercially available HIP4080A datasheet as a guide. The rad hard version is based on this part although not the same design or die. Still, the curves in the datasheet should get you in the ballpark and there is a lot of other useful info in ...
