CPC1596 Application Diagram 1 NC 4 NC CPC1596 2 LED+ 3 LED- CPC1596 570V, Optically Isolated Load-Biased Gate Driver Description The CPC1596 is an optically isolated, load-biased Gate Driver that requires no additional power supply to bias the external MOSFET gates; in the off-state it regulates the voltage drawn from the load (up to 570V) down to 12.2V for internal use. It is specifically designed for low duty cycle switching applications such as an optically isolated DC relay using a single MOSFET or an AC relay with two MOSFETs. The CPC1596 accomplishes very fast MOSFET turn-on by supplying charge stored in 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 internal optocoupler keeps the MOSFET active for as long as sufficient input control current is applied assuring very low-frequency operation. When the MOSFET is turned off, the storage capacitor charges from the load voltage via the regulated internal voltage in preparation for the next turn-on. Provided in a small, 8-pin package and requiring no separate power supply, the CPC1596 provides a flexible design solution that minimizes PCB real estate.
