HIP4080AIBZT

The HIP4080A is a high frequency, medium voltage FullBridge N-Channel FET driver IC, available in 20 lead plasticSOIC and DIP packages. The HIP4080A includes an inputcomparator, used to facilitate the “hysteresis” and PWMmodes of operation. Its HEN (high enable) lead can forcecurrent to freewheel in the bottom two external powerMOSFETs, maintaining the upper power MOSFETs off. Since it can switch at frequencies up to 1MHz, the HIP4080Ais well suited for driving Voice Coil Motors, switching poweramplifiers and power supplies. HIP4080A can also drive medium voltage brush motors, andtwo HIP4080As can be used to drive high performancestepper motors, since the short minimum “on-time” canprovide fine micro-stepping capability. Short propagation delays of approximately 55ns maximizecontrol loop crossover frequencies and dead-times whichcan be adjusted to near zero to minimize distortion, resultingin precise control of the driven load.
