HIP4081
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.
See Application Note AN9325 for HIP4081, Intersil Answer-
FAX, (407) 724-7800, document #99325. Intersil web home
page: http://www.semi.intersil.com
Similar part HIP4081A includes undervoltage circuitry which
does not require the circuitry shown in Figure 30 of this data
sheet.
