Description
The INT100 half-bridge driver IC provides gate drive for
external low-side and high-side MOSFET switches. The INT100
provides a simple, cost-effective interface between low-voltage
control logic and high-voltage loads. The INT100 is designed
to be used with rectified 110 V or 220 V supplies. Both high-
side and low-side switches can be controlled independently
from ground-referenced 5 V logic inputs.
Built-in protection logic prevents both switches from turning
on at the same time and shorting the high voltage supply. Pulsed
internal level shifting saves power and provides enhanced noise
immunity. The circuit is powered from a nominal 15 V supply
to provide adequate gate drive for external N-channel MOSFETs.
A floating high-side supply is derived from the low-voltage rail
by using a simple bootstrap technique.
Applications for the INT100 include motor drives, electronic
ballasts, and uninterruptible power supplies. Multiple devices
can also be used to implement full-bridge and multi-phase
configurations.
The INT100 is available in a 16-pin plastic SOIC package.
