SM8029

Optically Coupled

Dual MOSFET Driver

w/Discharge Circuit

Description

The SM8029 is composed of two distinct MOSFET drivers

in a single package. Each driver circuit 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

PDAs assures quick discharge of MOSFETs, providing fast

turn-off times. This device can be used as two separate

drivers, or can be wired as a single enhanced driver with

either greater photo current or photo voltage output.

The SM8029 comes standard in a compact 8 pin DIP

package making it ideal for high-density board applications.
