HIP4081 - 80V/2.5A Peak/ High Frequency Full Bridge FET Driver

General Description

The HIP4081 is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages.

The HIP4081 can drive every possible switch combination except those which would cause a shoot-through condition.

Key Features

  • Independently Drives 4 N-Channel FET in Half Bridge or Full Bridge Configurations.
  • Bootstrap Supply Max Voltage to 95VDC.
  • Drives 1000pF Load at 1MHz in Free Air at 50oC with Rise and Fall Times of Typically 10ns.
  • User-Programmable Dead Time.
  • On-Chip Charge-Pump and Bootstrap Upper Bias Supplies.
  • DIS (Disable) Overrides Input Control.
  • Input Logic Thresholds Compatible with 5V to 15V Logic Levels.
  • Very Low Power Consumption A.

HIP4081 November 1996 80V/2.5A Peak, High Frequency Full Bridge FET Driver Description The HIP4081 is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4081 can drive every possible switch combination except those which would cause a shoot-through condition. The HIP4081 can switch at frequencies up to 1MHz andssssss is well suited to driving Voice Coil Motors, high-frequency Class D audio amplifiers, and power supplies. For example, the HIP4081 can drive medium voltage brush motors, and two HIP4081s can be used to drive high performance stepper motors, since the short minimum “on-time” can provide fine micro-stepping capability.
