Description
The CPC1560 is a Single Pole, Normally Open
(1-Form-A) optically isolated MOSFET switch that
provides fast turn-on of loads up to 600mADC in the
DC-Only configuration or 300mArms in the AC/DC
configuration; active current-limiting circuitry; and
3750Vrms of input to output isolation.
Turn-on is minimized with the use of an optional
external storage capacitor that provides the necessary
charge required by the internal switching MOSFETs.
The device charges this capacitor through bootstrap
diodes from the load voltage thereby alleviating the
need for an additional power supply. A fast, but slightly
slower turn-on is available without the external charge
storage capacitor.
The CPC1560 incorporates current limiting and
thermal shutdown circuitry for improved survivability in
harsh environments and is designed to pass
regulatory voltage surge requirements when provided
with appropriate over-voltage protection.
Designed specifically for environmentally demanding
AC and DC applications where printed circuit board
space is at a premium and additional power supplies
are not available, the CPC1560 is an ideal solution.
