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.
