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.
