Description
The IX2127 is a high-voltage, high-speed power
MOSFET and IGBT driver. High-voltage level-shift
circuitry enables this device to operate up to 600V.
Clare’s proprietary common-mode design techniques
provide stable operation in high dV/dt noise
environments.
An on-board comparator can be used to detect an
over-current condition in the driven MOSFET or IGBT
device, and then shut down drive to that device. An
open-drain output, FAULT
, indicates that an
over-current shutdown has occurred.
The gate driver output typically can source 250mA
and sink 500mA, which is suitable for fluorescent lamp
ballast, motor control, SMPS, and other converter
drive topologies.
The IX2127 is provided in 8-pin DIP and 8-pin SOIC
packages, and is available in Tape & Reel versions.
See ordering information below.

3 Manufacturing Information
3.1 Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. Clare classified
all of its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint
industry standard, IPC/JEDEC J-STD-020, in force at the time of product evaluation. We test all of our
products to the maximum conditions set forth in the standard, and guarantee proper operation of our
devices when handled according to the limitations and information in that standard as well as to any limitations set
forth in the information or standards referenced below.
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced
product performance, reduction of operable life, and/or reduction of overall reliability.
This product carries a Moisture Sensitivity Level (MSL) rating as shown below, and should be handled according to
the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.
3.2 ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard
JESD-625.
3.3 Reflow Profile
This product has a maximum body temperature and time rating as shown below. All other guidelines of
J-STD-020 must be observed.
3.4 Board Wash
Clare recommends the use of no-clean flux formulations. However, board washing to remove flux residue is
