STMicroelectronics Dual-Channel Digital Signal Isolator Improves Circuit Configuration Flexibility

Introduction

STMicroelectronics has unveiled a new dual-channel digital signal isolator that will help engineers designing systems that require far-reaching protection from power-supply noise. The STPCIs-2i isolator has two channels, with each channel supporting a variety of differential data protocols. It has been designed to improve flexibility, allowing the circuit configurators to select any combination of data protocols and transmitters required by their system.

Features of IC Chip

The dual-channel device is configured via the transmitter-selection pins on each channel, which are used to select the specific data protocol and the corresponding transmitter that needs isolation. It is also flexible in terms of its operating power, as the STPCIs-2i can draw power from both 3.3V and 5V sources. Other features of the STPCIs-2i include EMI/RFI protection on the input and output lines, and a wide line-isolation voltage range of up to 2.5 kV.

The STPCIs-2i isolator also offers high temperature and humidity resistance, as well as high electromagnetic compatibility (EMC) performance, making it suitable for industrial applications with strict EMC requirements. It also helps to reduce power consumption and can reach up to 1 Mbps. With its low power consumption and excellent EMC performance, this isolator eliminates the risk of malfunctions in noisier environments.

Benefits of the IC Chip

The STPCIs-2i isolator can be used in various application scenarios such as automotive, factory automation, and industrial IoT systems. It can protect electronic systems from interference and thermal stress, enabling reliable operation. Additionally, it is designed to reduce power consumption and provide greater flexibility in circuit configurations, allowing system designers a greater control over their systems.

The STPCIs-2i is also available in a “DIP-compatible” package for low-cost integration into older applications, or for production in smaller quantities, and occupies minimal PCB space. It helps engineers to reduce system complexity and cost, as well as controlling power consumption.

Conclusion

STMicroelectronics' STPCIs-2i is a dual-channel digital signal isolator that offers a variety of features, such as EMI/RFI protection, wide line-isolation voltage range, high EMC performance and a selection pin-based protocol selection. It also helps to reduce power consumption while providing greater flexibility in circuit configurations. This makes the STPCIs-2i suitable for a wide range of applications, such as automotive, factory automation, and industrial IoT.
