HIP4081

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.
