Digital Isolators are devices that isolate electronic or electrical circuits from each other with the aim of ensuring safety of personnel and systems in sensitive environments. The HCPL-0900 is a quad digital isolator designed for use in industrial and automotive applications.

The 950-MHz HCPL-0900 quad digital isolator is designed to provide protection against high voltage transients and protect against electrostatic discharge. Each channel contains a high-performance switch for high-speed digital datatransmission of up to 2 Mbps. The device’s specification also includes a low power consumption of <30 μA at a 5V supply voltage.

The HCPL-0900 has wide operating temperature range of –40° to +125°C, making it suitable for a variety of commercial and industrial applications. The device also offers high creepage and clearance distance of 8.0 mm or more, and low isolation capacitance for high ESD immunity.

The HCPL-0900 has two isolation channels per package, each having its own transformer. Each channel has five signal pins, an isolated power supply, and two common pins for ground. The design provides a higher degree of isolation and a lower power consumption than other isolated device types.

The HCPL-0900’s design utilizes high-speed antenna switches to ensure input and output signals remain isolated regardless of the operating environment. Instead of using an opto-isolator, the device employs a transformer to ensure isolated signal integrity. The transformer also provides galvanic isolate of the power supply between channels.

The HCPL-0900 is capable of providing up to 8Mbps board-to-board communication, and up to 10Mbps with the use of a spread spectrum protocol. The device features various modes such as one-time programming, S-curves, and dynamic current limiting. TheHCPL-0900 also features an open drain output that can be used for voltage level shifting.

The HCPL-0900 offers a wide variety of applications and advantages for industrial and automotive applications. It is ideal for EMC and EMI considerations, high voltage isolation, and protection against electrostatic discharge. The device also provides a high level of isolation, low power consumption, and fast, reliable data transmission over distance.

Thanks to its wide operating temperature, high creepage and clearance, and low isolation capacitance, the HCPL-0900 digital isolator is the perfect choice for applications that demand these features. It is the ideal choice for a variety of industrial and automotive applications.
