Datasheet Summary
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 es standard in a miniature 4 pin SOP package.
Applications
- Isolated means to drive discrete power MOSFETs
