SM4209

SM4209 Optically Coupled MOSFET Driver w/Discharge Circuit Description The SM4209 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 SM4209 comes standard in a miniature 4 pin SOP package. Applications  Isolated means to drive discrete power MOSFETs  Lighting Controls  Process Control Modules  Solid State Relays  Solenoid Controls Schematic Diagram Features  Miniature 4 pin SOP package  Built in active discharge circuit for fast turn-off  Fast Turn-On  12V Gate Drive Voltage  High Input-to-Output Isolation (1.5kVRMS)  Long Life / High Reliability  RoHS / Pb-Free / REACH Compliant Agency Approvals UL / C-UL: VDE: File # E201932 File # 40035191 (EN 60747-5-2) Absolute Maximum Ratings The values indicated are absolute stress ratings.
