N/C
The INT200 Low-side driver IC provides gate drive for an
externallow-sideMOSFETswitchandhigh-sidelevelshifting.
WhenusedinconjunctionwiththeINT201high-sidedriver,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.

ORDERING INFORMATION
Built-in protection logic prevents both switches from turning
onatthesametimeandshortingthehighvoltagesupply. Pulsed
level shifting saves power and provides enhanced noise
immunity. The circuit is powered from a nominal 15 V supply
