The HIP4080 is a high frequency, medium voltage Full Bridge
N-Channel FET driver IC, available in 20 lead plastic SOIC and
DIP packages. The HIP4080 includes an input comparator,
used to facilitate the “hysteresis” and PWM modes of operation.
Its HEN (high enable) lead can force current to freewheel in the
bottom two external power MOSFETs, maintaining the upper
power MOSFETs off. Since it can switch at frequencies up to
1MHz, the HIP4080 is well suited for driving Voice Coil Motors,
switching amplifiers in class D high-frequency switching audio
amplifiers and power supplies.
HIP4080 can also drive medium voltage brush motors, and
two HIP4080s can be used to drive high performance step-
per 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 precise control of the driven load.
The similar HIP4081 IC allows independent control of all 4
FETs in an Full Bridge configuration.

Similar part, HIP4080A, includes under voltage circuitry
which doesn’t require the circuitry shown in Figure 30 of this
data sheet.
