Typical Application 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 MOS...
