Photo-Voltaic MOSFET Drivers
Also referred to as MOSFET Gate Drivers or Gate Drive Optocouplers, SSO Photo-Voltaic
MOSFET Drivers are an optically-isolated means of driving discrete MOSFETs. Unlike
conventional MOSFET Drivers, Photo-Voltaic MOSFET Drivers require no complex and costly
external power supply circuitry to operate.
Rather, SSO Photo-Voltaic MOSFET Drivers operate by application of a low power signal
from the primary side of the isolation barrier, which turns on an input LED optically
coupled to SSO’s proprietary IC. This IC provides an output voltage used to drive the
gate of a discrete MOSFET. The integrated rapid discharge circuit of the IC guarantees
fast turn-off times.
Use of SSO MOSFET Drivers simplifies circuit designs through reduced drive circuit
complexity, cost and board space, when compared to alternative techniques for isolated
switching of discrete MOSFETs.
Moreover, SSO MOSFET Drivers allows designers the flexibility to create discrete SSRs
by choosing the isolation value and MOSFET gate voltages separate from the discrete
MOSFET to be driven.
SSO MOSFET Drivers are offered in 4 pin SOP, 6 pin DIP/SMD and 8 pin DIP/SMD packages.
