SI8652ED-B-IS

SI8652ED-B-IS is Silicon Labs’ two-channel digital isolator (iCoupler family). It provides galvanic isolation between two logic domains, allowing two independent signals to cross an isolation barrier without a direct electrical connection.
Key points
- Two isolated channels: each channel transfers a logic signal from the input side to the output side.
- Independent side supplies: supports separate V on the primary and secondary sides, enabling safe interfacing across voltage domains.
- Protection and performance: low propagation delay, low power, wide operating temperature, and built-in protection suitable for noisy or high-voltage environments.
- Package and labeling: “B” indicates the package style and “IS” denotes isolated/industrial-grade device.
Typical uses
- Isolated interfaces for microcontrollers, sensors, and drivers in industrial, automotive, and power-electronics applications.
- Isolated communications links (e.g., SPI/I2C/ GPIO-style signals) across voltage barriers.
Note
- For exact electrical ratings (isolation voltage, input/output ranges, timing, and recommended operating conditions) and pinout, consult the SI8652ED-B-IS datasheet.

SI8652ED-B-IS is a galvanically isolated digital isolator. Typical application areas include:
- Industrial automation and motor control (isolating controllers from field devices)
- Power electronics and switch-mode power supplies (isolated control/feedback and gate-drive interfaces)
- Embedded systems (isolated SPI/I2C/UART and general I/O)
- Medical equipment (patient-safety isolation and EMI robustness)
- Automotive and electrified vehicles (high-voltage sensor/ECU isolation)
- Data communications and telecom equipment (robust isolation in noisy environments)
These use cases exploit safe, high-speed, point-to-point isolation between digital domains.
