High Voltage Half-Bridge
Gate Driver
Description
The IX21844 is a high voltage IC that can drive high
speed MOSFETs and IGBTs that operate up to
+600V. The IX21844 is configured with dependent
high-side and low side referenced output channels
which can source 1.4A and sink 1.8A. The floating
high-side channel can drive an N-channel power
MOSFET or IGBT 600V from the common reference.
Manufactured on IXYS Integrated Circuits Division's
proprietary high-voltage BCDMOS on SOI (silicon on
isolator) process, the IX21844 is extremely robust and
virtually immune to negative transients. The UVLO
circuit prevents the turn-on of the MOSFET or IGBT
until there is sufficient VBS or VCC supply voltage. A
programmable dead-time can be set between 400ns
and 5us to insure that both the high-side and low-side
power MOSFET or IGBT are not enabled at the same
time. Propagation delays are matched for use in high
frequency applications.
The IX21844 is available in 14-pin DIP and 14-pin
SOIC (narrow body) packages. The 14-pin SOIC
(narrow body) package is also available in tape & reel.
