| Data Sheet No. PD10054 Series PVI-N 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 switching with optical isolation between the low-level driving 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 higher 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 packaged in 8-pin, molded DIP packages and available with either through-hole or surface-mount ("gull-wing") leads, in plastic shipping tubes.

Alternatively, the two ouptut of the PVI1050 may be connected in parallel to produce a 5.0-volt ouput with a 10A minimum short circuit current. The two outputs of the PVI1050N may be applied separately with a maximum 1200VDC between the outputs. Input-to-output isolation to either output is 2500V (RMS). 4 www.irf.com Series PVI-N Case Outlines PVI1050N 01-2004 03 PVI1050NS www.irf.com 01-2005 03 5 Series PVI-N Case Outlines PVI5050N/PVI5080N 01-2013 00 (MS-001AB) PVI5050NS/PVI5080NS 6 01-2019 00 11/29/2001 www.irf.com |
