Functional Diagram
Description
The HCPL‑T250 contains GaAs LED. The LED is optically
coupled to an integrated circuit with a power output stage.
This optocoupler is ideally suited for driving power IGBTs
and MOSFETs used in motor control inverter applications.
The high operating voltage range of the output stage
provides the drive voltages required by gate controlled
devices. The voltage and current supplied by this optocou‑
pler makes it ideally suited for directly driving IGBTs with
ratings up to 1200 V/25 A. For IGBTs with higher ratings,
the HCPL‑T250 can be used to drive a discrete power stage
which drives the IGBT gate.
