SM4206
Optically Coupled
MOSFET Driver
w/Discharge Circuit
Description
The SM4206 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 SM4206 comes standard in a miniature 4 pin SOP
package.
