HCPL-4504-000E

高CMR高速光电耦合器

Description

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.

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. The CTR, propagation delay, and CMR are specified both for TTL and IPM conditions which are provided for ease of application.

Features

• Short propagation delays for TTL and IPM applications

• 15 kV/μs minimum Common Mode Transient immunity at VCM = 1500 V for TTL/load drive

• High CTR at TA = 25°C

Applications

• Inverter circuits and Intelligent Power Module IPM interfacing: High Common Mode Transient immunity > 10 kV/μs for an IPM load/drive and tPLH - tPHL Specified see Power Inverter Dead Time section

• Line receivers: Short propagation delays and low in put-output capacitance

• High speed logic ground isolation: TTL/TTL, TTL/CMOS, TTL/LSTTL

• Replaces pulse transformers: Save board space and weight

• Analog signal ground isolation: Integrated photodetector provides improved linearity over phototransistors
