Description:

The photovoltaic MOSFET driver is a State-of- the-Art, optically coupled floating power source used primarily to control

MOSFETs when electrical isolation between input and output is required.

In addition to the infrared LED and photovoltaic diode array, each of the DD (Dynamic Discharge) products contains

circuitry that rapidly discharges the power MOSFET gate when the LED is deactivated. The unique rapid discharge

features of the photovoltaic MOSFET drivers make them particularly useful for high side switching of N-channel

MOSFETs in solid-state relays, DC motor control and switching regulator applications.

The typical input circuit to the LED is a limiting resistor connected in series with the LED. When activated, the LED

emits infrared light towards the photovoltaic diode array, which then responds by generating an open circuit voltage (V_oc)

and disabling the turn off circuitry. The self-limiting photovoltaic output of the diode array is floating and therefore, can

be safely applied directly to the gate and source of a MOSFET, regardless of the source potential of the MOSFET. When

the LED is deactivated, the active turn off circuit discharges the capacitive input of the MOSFET. The active turn off

circuitry is designed such that the turn off time of the MOSFET is relatively independent of the input capacitance of the

MOSFET over a range of 300 to 5000 pF. Standard packages include low cost plastic mini-dips and hermetic 8-pin DIP

ceramic side brazed.
