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.
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.
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.
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.
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.
