General Description
The TX-02-4400PI/JI is a dual winding interface transformer
designed to be used with the IXYS IXBD4410/IXBD4411chip set.
This ISOSMART chip set controls the gates of two Power
MOSFETs or IGBTs connected in a half-bridge (phase-leg)
configuration. This signal transformer transfers information
between the two chips with greater than 2500V (RMS) isolation.
The TX02-4400PI is available in the standard 8-pin DIP package
(TX02-4400PI) and the 8-pin DIP Gullwing package (TX02-
4400JI)
