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. The ISO-GATE
TM
is a state-of-the-art opto-
isolator incorporating DIONICS' photovoltaic (PV) diode arrays and an infrared LED. The diode array is a unique I.C.
consisting of series-connected photovoltaic diodes. The diodes are completely isolated from each other and from their
common substrate by means of SiO
2
Dielectric Isolation (DI). These photovoltaic output chips are electrically isolated but
optically coupled to the LED.
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
(Voc). This Voc is floating and is therefore completely isolated. The Voc value depends on the LED input drive and load
impedance. DIONICS, Inc offers a wide variety of package styles including low-cost plastic Mini-DIP's, high reliability
TO-5 metal cans, 8-pin ceramic side brazed DIP's and ceramic chip carriers for hybrid manufacturers. Other custom
packages and custom designs are also available.
