DESCRIPTION

The CT- 202D 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. An external resistor connected between the gate and source of the Mosfet will discharge the gate and keep it turned off when them is no led input.

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, which 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 an LOW impedance state.

The CT - 202D is packaged in an 8 pin plastic dip package, other package types and high- REL versions are available, please consult our sales department for additional information.
