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.
