November 1996
80V/2.5A Peak, High Frequency
Full Bridge FET Driver
Description
The HIP4081 is a high frequency, medium voltage Full
Bridge N-Channel FET driver IC, available in 20 lead plastic
SOIC and DIP packages. The HIP4081 can drive every pos-
sible switch combination except those which would cause a
shoot-through condition. The HIP4081 can switch at fre-
quencies up to 1MHz andssssss is well suited to driving
Voice Coil Motors, high-frequency Class D audio amplifiers,
and power supplies.
For example, the HIP4081 can drive medium voltage brush
motors, and two HIP4081s can be used to drive high perfor-
mance 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 HIP4080, includes an on-chip input com-
parator to create a PWM signal from an external triangle
wave and to facilitate “hysteresis mode” switching.

Similar part HIP4081A includes undervoltage circuitry which
does not require the circuitry shown in Figure 30 of this data
sheet.
