High-Voltage
Power MOSFET & IGBT Driver
Driver Characteristics
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.
Features
• Floating Channel Designed for Bootstrap Operation
up to 600V
• Tolerant to Negative Transient Voltages; dV/dt
Immune
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.
• Undervoltage Lockout
• 3.3V, 5V, and 12V Input Logic Compatible
• Open-Drain FAULT Indicator Pin Shows
Over-Current Shutdown
• Output in Phase with the Input
The IX2127 is provided in 8-pin DIP and 8-pin SOIC
packages, and is available in Tape & Reel versions.
See ordering information below.
Applications
• High-Speed Gate Driver
• Motor Drive Inverter
