Overview
Description
The HIP4080A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4080A includes an input comparator, 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. Since it can switch at frequencies up to 1MHz, the HIP4080A is well suited for driving Voice Coil Motors, switching power amplifiers and power supplies. HIP4080A can also drive medium voltage brush motors, and two HIP4080As can be used to drive high performance stepper motors, since the short minimum on-time can provide fine micro-stepping capability. Short propagation delays of approximately 55ns 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. The similar HIP4081A IC allows independent control of all 4 FETs in a Full Bridge configuration.

HIP4080, HIP4080A, HIP4081 or HIP4081A Spice Model
There is an old Spice model floating around the web and I have attached it for your convenience. It is provided with no warranty and has not been verified. Make sure you read the entire "readme.txt". Below are excerpts from that: MACRO MODELS FOR HIP4080, HIP4080A, HIP4081, AND HIP4081A ...

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 ...

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 ...
