80V/2.5A Peak, High Frequency
Full Bridge FET Driver
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 power amplifiers and power supplies.
HIP4080 can also drive medium voltage brush motors, and two
HIP4080s 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
precise control of the driven load.
The similar HIP4081 IC allows independent control of all 4
FETs in an Full Bridge configuration.
See also, Application Note AN9324 for the HIP4080.
Similar part, HIP4080A, includes under voltage circuitry
which doesn’t require the circuitry shown in Figure 30 of this
data sheet.
