Semitronics
Description:
The CT222ADM is an isolated dual photovoltaic
MOSFET driver used when a high degree of
electrical isolation is required.
The driver can isolate the MOSFET from more
sensitive control circuitry and enable the source
and drain connections to reach any potential within
the range of the isolation voltage. High photo
efficiency produces fast turn on. A low off state
impedance insures fast turn off and immunity from
dv/dt when the MOSFET is in the off state.
The CT222ADM is packaged in an 8 pin hermetically
sealed ceramic dip and is designed for high
reliability applications.
