data sheet no. pd10054 revg series pvi-npbf photovoltaic isolator single and dual channel 5-10 volt output general description the pvi series photovoltaic isolator generates an electrically isolated dc voltage upon receipt of a dc input signal. it is capable of directly driving gates of power mosfets or igbts. it utilizes a monolithic integrated circuit photovoltaic generator of novel construction as its output. the output is controlled by radiation from a gaalas light emitting diode (led), which is optically isolated from the photovoltaic generator. the pvi series is ideally suited for applications requiring high-current and/or high-voltage switchin g with optical isolation between the low-level drivin g circuitry and high-energy or high-voltage load circuits. it can be used for directly driving gates of power mosfets. the dual-channel device allows its outputs to drive independent discrete power mosfets, or be connected in parallel or in series to provide highe r current drive for power mosfets or higher voltage drive for igbts. the pvi series photovoltaic isolators employ fast turn-off circuitry. these pvi series photovoltaic isolators are package d in 8-pin, molded dip packages and available with ei ther thru-hole or surface-mount (gull-wing) leads, in plastic shipping tubes.applications features ? isolated voltage source ? monolithic construction ? up to 8 a output ? single or dual output ? solid-state reliability part identiicationpvi1050npbf pvi5050npbf pvi5080npbf PVI1050NSPBF pvi5050nspbf pvi5080nspbf pvi1050ns-tpbf thru-hole surface-mount (gull-wing) surface-mount, tape and reel www.irf.com 1 ? load distribution ? industrial controls ? current-to-voltage conversion ? custom solid-state relay downloaded from: http:///
