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 power

amplifiers and power supplies.

HIP4080A can also drive medium voltage brush motors, and

two HIP4080As 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 maximize

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 a Full Bridge configuration.

The Application Note for the HIP4080A is AN9404.
