DESCRIPTION
The VOM1271 is a stand-alone optically isolated MOSFET
driver. Unlike conventional MOSFET drivers, which require
an external power supply to provide V_CC and or V_DD rails to
the driver itself, the VOM1271 obtains all the required
current to drive its internal circuitry from the LED current on
the low voltage primary side of the isolation barrier. This
saves the designer the space and cost associated with
providing one or more external power supplies. The
VOM1271 also integrates a turn-off circuit internal to the
component itself, thus doing away with the need for
additional components in order to increase the overall
switching speed by decreasing the turn-off time. These
features, combined with a small SOP4 package, provide
designers with a small footprint, highly integrated isolated
gate driver solution for a large variety of MOSFET drive
applications.
