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.
