Description

The CPC1580 optical gate driver provides isolated

control of a discrete power MOSFET transistor without

the need of an external power supply. Control of the

power MOSFET transistor is accomplished by the

application of sufficient input LED current to activate

the driver circuitry.

On the load side, an external storage capacitor and an

internal bootstrap diode enable the internal

photovoltaic and gate driver circuitry to provide fast

output switching characteristics by supplying the

charge necessary to satisfy the MOSFET’s bias

requirements.

Provided in a small 8-pin package, the CPC1580
