HIP4080A

80V/2.5A Peak, High Frequency

Full Bridge FET Driver

Description

The HIP4080A is a high frequency, medium voltage Full Bridge

N-Channel FET driver IC, available in 20 lead plastic SOIC and

DIP packages. The HIP4080A 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 HIP4080A is well suited for driving Voice Coil

Motors, switching amplifiers in class D high-frequency switching

audio amplifiers and power supplies.

HIP4080A can also drive medium voltage brush motors, and

two HIP4080As 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 HIP4081A IC allows independent control of all 4

FETs in an Full Bridge configuration.

The Application Note for the HIP4080A is AN9404.
