LTV-3150
0.6A Output Current, High CMR,
Gate Drive Optocoupler
Apr 2011
Description
The LTV-3150 optocoupler is ideally suited
for driving power IGBTs and MOSFETs
used in motor control inverter applications
and inverters in power supply system. It
contains an AlGaAs LED optically coupled to
an integrated circuit with a power output
stage. The 0.6A peak output current is
capable of directly driving most IGBTs with
ratings up to 1200 V/50 A. For IGBTs with
higher ratings, the LTV-3150 series can be
used to drive a discrete power stage which
drives the IGBT gate.
The Optocoupler operational parameters
are guaranteed over the temperature range
from -40^oC ~ +100^oC.
