Description
The INT200 Low-side driver IC provides gate drive for an
external low-side MOSFET switch and high-side level shifting.
When used in conjunction with the INT201 high-side driver, the
INT200 provides a simple, cost-effective interface between
low-voltage control logic and high-voltage loads. The INT200
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 on the
low side driver.
Built-in protection logic prevents both switches from turning
on at the same time and shorting the high voltage supply. Pulsed
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.
Applications include motor drives, electronic ballasts, and
uninterruptible power supplies. The INT200 can also be used
to implement full- bridge and multi-phase configurations.
The INT200 is available in 8-pin plastic DIP and SOIC packages.
