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