HS-4080ARH

Radiation Hardened Full Bridge

N-Channel FET Driver

The HS-4080ARH is a monolithic, high frequency, medium

voltage Full Bridge N-Channel FET Driver IC. The device

includes a TTL-level input comparator, which can be 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. The HS-4080ARH is well suited for use

in distributed DC power supplies and DC to DC converters,

since it can switch at high frequencies.

These devices can also drive medium voltage motors, and

two HS-4080ARHs can be used to drive high performance

stepper motors, since the short minimum “on-time” can

provide fine micro-stepping capability.

Short propagation delays 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.

Constructed with the Intersil dielectrically isolated Rad Hard

Silicon Gate (RSG) process, these devices are immune to

Single Event Latch-up and have been specifically designed

to provide highly reliable performance in harsh radiation

environments. Complete your design with radiation

hardened MOSFETs from Intersil.

Specifications for Rad Hard QML devices are controlled

by the Defense Supply Center in Columbus (DSCC). The

SMD numbers listed here must be used when ordering.
