Logic Output Optoisolators

HCPL-0300 Description

The HCPL-0300 from Broadcom is a high-performance, single-channel optoisolator designed for applications requiring robust signal isolation and fast data transmission. It features an open-collector, Schottky-clamped output, ensuring low propagation delay and high noise immunity. With a voltage isolation rating of 3750Vrms, it provides reliable protection against high-voltage transients, making it suitable for industrial and automotive environments. The device operates at a 5MBd data rate and supports a supply voltage range of 4.75V to 5.25V, aligning with standard TTL/CMOS logic levels. Its DC input type and 100V/µs common-mode transient immunity (CMTI) ensure stable performance in electrically noisy conditions.

HCPL-0300 Features

• High-Speed Performance: Rise/fall times of 40ns/20ns (Typ) and propagation delays of 160ns/200ns (Max) enable efficient signal transmission.
• Robust Isolation: 3750Vrms isolation voltage and 100V/µs CMTI enhance reliability in high-noise environments.
• Schottky-Clamped Output: Open-collector output with 25mA current drive ensures compatibility with logic circuits while minimizing power dissipation.
• Low Power Consumption: Forward voltage of 1.3V (Typ) and 5mA (Typ) input current optimize energy efficiency.
• Surface-Mount Package: 8-pin SOIC package (tube packaging) facilitates easy integration into compact PCB designs.
• REACH & ECCN Compliance: REACH unaffected and EAR99 classification ensure global regulatory compliance.

HCPL-0300 Applications

The HCPL-0300 excels in applications demanding high-speed, noise-immune signal isolation, such as:

• Industrial Automation: Isolating PLCs, motor drives, and sensors in high-voltage systems.
• Medical Equipment: Ensuring patient safety in diagnostic and monitoring devices.
• Automotive Systems: Protecting communication buses (CAN, LIN) from voltage spikes.
• Power Electronics: Gate drive isolation in inverters and switching power supplies.
• Digital Communication Interfaces: Isolating RS-485, I²C, or SPI signals in noisy environments.

Conclusion of HCPL-0300

The HCPL-0300 stands out for its high-speed performance, robust isolation, and low-power operation, making it a versatile solution for critical isolation tasks. Its Schottky-clamped output and excellent CMTI provide superior noise immunity, while its compact form factor ensures easy integration. Ideal for industrial, medical, and automotive applications, this optoisolator combines reliability with efficiency, meeting the demands of modern electronic systems.
