80V/2.5A Peak, High Frequency Full Bridge FET Driver  
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.  
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 50°C with Rise  
and Fall Times of Typically 10ns  
• User-Programmable Dead Time  
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.  
• On-Chip Charge-Pump and Bootstrap Upper Bias  
Supplies  
• DIS (Disable) Overrides Input Control  
• Input Logic Thresholds Compatible with 5V to 15V Logic  
Levels  
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.  
• Very Low Power Consumption  
• Undervoltage Protection  
• Pb-free Available  
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.  
Applications  
The Application Note for the HIP4081A is the AN9405.  
• Medium/Large Voice Coil Motors  
• Full Bridge Power Supplies  
• Switching Power Amplifiers  
• High Performance Motor Controls  
• Noise Cancellation Systems  
• Battery Powered Vehicles  
• Peripherals

NOTE: Intersil Pb-free products employ special Pb-free material  
sets; molding compounds/die attach materials and 100% matte tin  
plate termination finish, which is compatible with both SnPb and  
Pb-free soldering operations. Intersil Pb-free products are MSL  
classified at Pb-free peak reflow temperatures that meet or exceed  
the Pb-free requirements of IPC/JEDEC J Std-020B.
