IL485
Overview
- 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. The photo IC chip contains additional circuitry to enhance the switching speeds, (both turn on turn off). The optocoupler is packaged in a 6 pin DIP.
