SM6002 Optically Coupled MOSFET Driver w/Discharge Circuit Description The SM6002 consists of an input drive LED optically coupled to a photodiode array output designed to drive highly capacitive loads, including the gate of a power MOSFET. The active discharge circuit of the PDA assures quick discharge of MOSFETs, providing fast turn-off times. This device can be used in a wide variety of applications for which high levels of input are required for a MOSFET output. The SM6002 comes standard in a miniature 6 pin DIP package making it ideal for high-density board applications. Applications  Isolated means to drive discrete power MOSFETs  Lighting Controls  Process Control Modules  Solid State Relays  Solenoid Controls Schematic Diagram (+) Input 1 6 (+) DC Output (-) Inpu [ ... ]
