Description
The INT201 high-side driver IC provides gate drive for an
external high-side MOSFET switch. When used in conjunction
with the INT200 or INT202 low-side drivers, the INT201
provides a simple, cost-effective interface between low-voltage
control logic and high-voltage loads.
Built-in noise rejection circuitry shared between the INT201
and the INT200 or INT202 provides reliable operation in the
harshest industrial environments. The INT201 is powered from
a ground-referenced low-voltage supply. A floating supply is
derived from this rail by using a simple bootstrap technique to
provide adequate gate drive for the external N-channel MOSFET.
Applications include motor drives, electronic ballasts, and
uninterruptible power supplies. The INT201 can also be used
to implement full-bridge and multi-phase configurations.
The INT201 is available in 8-pin plastic DIP and SOIC packages.
