CPC1580

INTEGRATED CIRCUITS DIVISION Features Drives External Power MOSFET Low LED Current (2.5mA) Requires No External Power Supply Load Voltages up to 65V High Reliability Small 8-pin Surface Mount Package 3750Vrms Input/Output Isolation Flammability Rating UL 94 V-0 Applications Industrial Controls Instrumentation Medical Equipment Isolation Electronic Switching I/O Subsystems Appliances Approvals UL recognized component: File # E76270 CPC1580 Optically Isolated Gate Drive Circuit 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.
