IL485 OPTICALLY COUPLED HIGH SPEED MOSFET DRIVERS OPTOCOUPLER

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 outpu.
