HIP4081A

80V/2.5A Peak, High Frequency Full Bridge FET Driver

DATASHEET

The HIP4081A is a high frequency, medium voltage Full

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

SOIC and DIP packages. The HIP4081A can drive every

possible switch combination except those which would

cause a shoot-through condition. The HIP4081A can switch

at frequencies up to 1MHz and is well suited to driving Voice

Coil Motors, high-frequency switching power amplifiers, and

power supplies.

For example, the HIP4081A can drive medium voltage brush

motors, and two HIP4081As 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 rapid, precise control of the driven load.

A similar part, the HIP4080A, includes an on-chip input

comparator to create a PWM signal from an external triangle

wave and to facilitate “hysteresis mode” switching.

The Application Note for the HIP4081A is the AN9405.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
