MOSFET Gate Driver Integrated Circuit provides 3,750 Vrms of I/O isolation.

MOSFET Gate Driver Integrated Circuit provides 3,750 Vrms of I/O isolation.

Designed for remote switching of DC and low frequency loads where isolated power is unavailable, optically isolated Model CPC1590 uses bootstrap biasing technique to eliminate load-side power supply. External power MOSFET is controlled by application of 2.5-10 mA LED current to CPC1590, which activates internal load-side driver circuit. Housed in 8-pin package, IC provides blocking voltage rating...
