Description
The INT202 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
INT202 provides a simple, cost-effective interface between
low-voltage control logic and high-voltage loads. The INT202
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.
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 switched reluctance motor drives. The
INT202 can also be used to implement multi-phase
configurations.
The INT202 is available in 8-pin plastic DIP and SOIC packages.
