80V/2.5A Peak, High Frequency Full  
Bridge FET Driver  
Features  
• Independently Drives 4 N-Channel FET in Half Bridge or  
Full Bridge Configurations  
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.  
• 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  
• On-Chip Charge-Pump and Bootstrap Upper Bias  
Supplies  
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.  
• DIS (Disable) Overrides Input Control  
• Input Logic Thresholds Compatible with 5V to 15V Logic  
Levels  
• Very Low Power Consumption  
• Undervoltage Protection  
• Pb-free Available  
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.  
Applications  
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.  
• Medium/Large Voice Coil Motors  
• Full Bridge Power Supplies  
• Switching Power Amplifiers  
• High Performance Motor Controls  
• Noise Cancellation Systems  
• Battery Powered Vehicles  
• Peripherals  
The Application Note for the HIP4081A is the AN9405.

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.
