Overview
Description
The HIP4081A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4081A can drive every possible switch combination except those which would cause a shoot-through condition. The HIP4081A can switch at frequencies up to 1MHz and is well suited to driving Voice Coil Motors, high-frequency switching power amplifiers, and power supplies. For example, the HIP4081A can drive medium voltage brush motors, and two HIP4081As 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 maximizes control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting in rapid, precise control of the driven load. A similar part, the HIP4080A, includes an on-chip input comparator to create a PWM signal from an external triangle wave and to facilitate hysteresis mode switching.

HIP4081A Inputs do not control outputs
Hello, I have basically made a copy of the evaluation board for the HP4081A attached to a stepper motor. I use a PIC microcontroller to operate the AHI,ALI,BHI, and BLI pins of the HIP4081A, but the AHO,ALO,BHO, and BLO pins do not respond to the inputs ...

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 ...
