High CMR, High Speed Optocouplers
The HCPL-4504 and HCPL-0454 contain a GaAsP LED while the HCPL-J454 and HCNW4504 contain an AlGaAs LED. The LED is optically coupled to an integrated high gain photo detector.It contains a GaAsP LED. The LED is optically coupled to an integrated high gain photo detector. The CTR, propagation delay, and CMR are specified both for TTL and Intelligent Power Module (IPM) interface conditions for ease of application.
The HCPL-4504 series has short propagation delays and high CTR. The HCPL-4504 series also has a guaranteed propagation delay difference (tPLH-tPHL). These features make the HCPL-4504 series an excellent solution to IPM inverter dead time and other switching problems. This single channel, diode-transistor optocoupler is available in a SO-8 package. An insulating layer between a LED and an integrated photodetector provides electrical insulation between input and output.
Separate connections for the photodiode bias and output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base collector capacitance.
