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 su……
