80V/2.5A Peak, High Frequency Full Bridge FET Driver Evaluation Board

The HIP4080A/81AEVALZ evaluation board is used to demonstrate the HIP4080A and HIP4081A 80V/2.5A peak, high frequency full bridge FET drivers with charge pump and input comparators.

The HIP4080A and HIP4081A are high frequency, medium voltage full bridge N-channel FET driver ICs, available in 20 lead plastic SOIC and DIP packages. These FET drivers switch at frequencies up to 1MHz making them well suited for driving voice coil motors, switching power amplifiers and power supplies.

The HIP4080A includes an input comparator, used to facilitate the “hysteresis” and PWM modes of operation. The HIP4081A can drive every possible switch combination except those which would cause a shoot-through condition.

Key Features

  • Drives N-channel FET full bridge including high side chop capability (HIP4080A)
