DESCRIPTION

The CT - 201AD is an isolated 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 typical input circuit is a limiting resistor connected in series with the input Led. When activated, infrared energy is optically coupled to a photovoltaic diode array producing a voltage that charges the gate of the Mosfet being driven. When current to the led is turned off the gate of the Mosfet is discharged and held in a Low impedance state.

The CT - 201AD is packaged in a 6 pin plastic dip package, other package types and high- REL versions are available, please consult our sales department for additional information.
