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.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-99617. A “hot-link” is provided
on our homepage for downloading.
