CPC1590 Optically Isolated Gate Driver INTEGRATED CIRCUITS DIVISION Driver Characteristics Description Parameter Rating Units Input Current 2.5 mA Switching Speed (IF=5mA, MOS Input Capacitance=4nF) td(on) 12 td(off1) (VGS=2V) 125 td(off2) (VGS=1V) 210 s The CPC1590 accomplishes very fast MOSFET turn-on by supplying stored charge, from an external capacitor, to the MOSFET gate when input control current is applied to the device’s LED. After the MOSFET is turned on, photocurrent from the input optocoupler keeps it on for as long as sufficient input control current flows, so there is no low-frequency operating limit. When the MOSFET is turned off, the storage capacitor charges from the device’s regulated internal voltage in preparation for the next turn-on. Features • • • • • • • • • • 3750Vrms Input-to-Output Isolation Drives External Power MOSFET Low LED Current (2.5mA) Requires No External Power Supply Load Voltages up to 200V High Reliability Small 8-pin Surface Mount Flatpack Package Machine Insertable, Wave Solderable Tape and Reel Version Available Flammability Rating UL 94 V-0 Because it is provided in a small, 8-pin Flatpack package and requires no separate power supply, the CPC1590 provides a flexible design solution that consumes the least amount of PCB land area. Applications • • • • • The CPC1590 is a MOSFET Gate Driver that requires no external power supply: it regulates the input voltage drawn from the load (up to 200V), down to 12.2V for internal use. It is specifically designed for low duty cycle switching applications that drive up to 4nF of gate capacitance.
