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.
