GATE CHARGE MINIMIZED

DESCRIPTION

The PowerMESH

™II is the evolution of the first

generation of MESH OVERLAY

™. The layout re-

finements introduced greatly improve the Ron*area

figure of merit while keeping the device at the lead-

ing edge for what concerns swithing speed, gate

charge and ruggedness.

APPLICATIONS
