SM4203
Optically Coupled
MOSFET Driver
w/Discharge Circuit
Description
The SM4203 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 SM4203 comes standard in a miniature 4 pin SOP
package.
Applications
 Isolated means to drive discrete power MOSFETs
 Lighting Controls
 Process Control Modules
 Solid State Relays
 Solenoid Controls
