SM8021
Optically Coupled
Dual MOSFET Driver
w/Discharge Circuit
Description
The SM8021 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 SM8021 comes standard in a compact 8 pin DIP
package making it ideal for high-density board applications.
