CPC1596 570V, Optically Isolated Load-Biased Gate Driver INTEGRATED CIRCUITS DIVISION Driver Characteristics Description The CPC1596 is an optically isolated, load-biased Parameter Rating Units Gate Driver that requires no additional power supply to Input Current 2.5 mA bias the external MOSFET gates in the off-state it regulates the voltage drawn from the load (up to 570V) Switching Speed (I =5mA, MOSFET Input Capacitance=4nF) F down to 12.2V for internal use. It is specifically t d(on) 3 designed for low duty cycle switching applications such as an optically isolated DC relay using a single t (V =2V) d(off1) GB 365 s MOSFET or an AC relay with two MOSFETs. t (V =1V) 435 d(off2) GB The CPC1596 accomplishes very fast MOSFET turn-on by supplying charge stored in an external Features capacitor to the MOSFET gate when input control current is applied to the devices LED. After the Integrated 570V to 12.2V regulator circuit for driving MOSFET is turned on, photocurrent from the internal high-power, high-voltage MOSFETs eliminates the optocoupler keeps the MOSFET active for as long as need for auxiliary power supply sufficient input control current is applied assuring very Capable to source 9.9mA and sink 6mA gate-current low-frequency operation. When the MOSFET is turned to boost external MOSFET turn-on speed off, the storage capacitor charges from the load voltage via the regulated internal voltage in Enables using higher power MOSFETs preparation for the next turn-on. Only 2.5mA input LED current required Provided in a small, 8-pin package and requiring no 3750V Input-to-Output galvanic isolation RMS separate power supply, the CPC1596 provides a Small 8-pin DIP and Surface Mount Packages flexible design solution that minimizes PCB real estate.
