IXYS IX21844
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.| Part No. | IX21844 |

DESCRIPTION
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.
