Infineon BCM846S: A High-Performance Dual-Channel Digital Isolator for Robust Industrial Applications
In the demanding environment of modern industrial automation, motor drives, and power supply systems, ensuring reliable signal transmission across different voltage domains is critical. The Infineon BCM846S stands out as a high-performance dual-channel digital isolator specifically engineered to meet these challenges, offering exceptional noise immunity, high-speed data transmission, and robust isolation in a compact package.
Designed with reinforced isolation capabilities, the BCM846S provides a critical barrier between high-voltage and low-voltage sections of a circuit. It complies with international safety standards such as IEC 60747-17, offering isolation voltages up to 5.7 kVRMS and working voltages up to 1.5 kVRMS. This makes it an ideal solution for protecting sensitive microcontrollers and logic circuits from high-voltage transients and ground potential differences commonly found in industrial settings.

A key advantage of the BCM846S is its high common-mode transient immunity (CMTI), exceeding 100 kV/µs. This ensures data integrity is maintained even in the presence of extremely fast noise spikes, which are typical in noisy industrial environments with switching power electronics and motor drives. The device supports high data rates, up to 150 Mbps, enabling precise, real-time control communication without latency issues.
The integration of two independent isolation channels in one package provides design flexibility, allowing engineers to isolate bidirectional communication lines (e.g., SPI, UART) or multiple unidirectional signals while saving valuable board space. Furthermore, its wide supply voltage range (2.5 V to 5.5 V) facilitates easy interfacing with various logic families.
With its low power consumption and high reliability across an extended industrial temperature range (-40°C to +125°C), the BCM846S is built for longevity and stability in harsh applications. Its robust performance ensures system safety and operational continuity, reducing the risk of downtime in critical processes.
