描述
The HIP4080A/81AEVALZ evaluation board is used to demonstrate theHIP4080A andHIP4081A 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.
特性
- Drives N-channel FET full bridge including high-side chop capability (HIP4080A)
- Independently drives four N-channel FETs in half bridge or full bridge configurations (HIP4081A)
- Bootstrap supply max voltage to 95VDC
- Drives 1000pF load at 1MHz in free air at +50 °C with rise and fall times of typically 10ns
- User-programmable dead time
- Charge-pump and bootstrap maintain upper bias supplies
- DIS (Disable) pin pulls gates low
- Input logic thresholds compatible with 5V to 15V logic levels
- Very low power consumption
- Undervoltage protection
- Pb-free available
