IL485
OPTICALLY COUPLED HIGH SPEED MOSFET DRIVERS OPTOCOUPLER
FEATURES • Fast Turn On • Fast Turn Off • Low Input Current • Isolation Test Voltage, 5300 VACRMS APPLICATIONS • Motor Drive Controls • IGBT-predrivers • AC/DC Power Inverters DESCRIPTION The IL485 is a photovoltatic generator (optically coupled) designed to drive highly capacitive loads such as the gate of a power MOSFET transistor and at the same time provide isolation and floating voltage supply capability. The coupler consists of a GaAlAs light emitting diode as input control and a custom photo IC chip with photodiode arrary (PDA) as output device. When the LED is turned on, the emitted light produces a voltage in the PDA. The output of the PDA is used to drive the gate of a power MOSFET.
