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
provides 3750Vrms of input-to-output isolation.
