Data Sheet No. PD10054-B
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 thru-hole or surface-mount ("gull-wing") leads,
in plastic shipping tubes.

Application Note:
The outputs of the PVI1050N (pins 5-6 and 7-8) may be placed in series connection to produce a 10-volt output
with a 5A minimum short circuit current. Alternatively, the two ouptut of the PVI1050 may be connected in paral-
lel 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).
