CPC1580P

CPC1580 Optically Isolated Gate Drive Circuit INTEGRATED CIRCUITS DIVISION Features Description Drives External Power MOSFET The CPC1580 optical gate driver provides isolated Low LED Current (2.5mA) control of a discrete power MOSFET transistor without Requires No External Power Supply the need of an external power supply. Control of the Load Voltages up to 65V power MOSFET transistor is accomplished by the High Reliability application of sufficient input LED current to activate Small 8-pin Surface Mount Package the driver circuitry. 3750V Input/Output Isolation rms On the load side, an external storage capacitor and an internal bootstrap diode enable the internal Applications photovoltaic and gate driver circuitry to provide fast Industrial Controls output switching characteristics by supplying the Instrumentation charge necessary to satisfy the MOSFETs bias Medical Equipment Isolation requirements. Electronic Switching I/O Subsystems Provided in a small 8-pin package, the CPC1580 Appliances provides 3750V of input-to-output isolation. rms Approvals Ordering Information UL recognized component: File E76270 Part Description CPC1580P 8-Pin Flatpack (50/Tube) CPC1580PTR 8-Pin Flatpack (1000/Reel) Figure 1.
