Key Features
- Reinforced isolation rated at 5 kVrms protects CAN FD bus nodes from high-voltage transients in industrial and automotive environments
- Supports CAN FD data rates up to 5 Mbps with propagation delay under 150 ns enabling fast, deterministic network timing
- Integrated bus fault protection and 70 mA maximum supply current in a space-saving 8-pin SOP package
Applications
XISO1044BDR is designed for CAN FD networks in motor drives, solar inverters, and industrial robots where the controller side must be galvanically isolated from the high-voltage bus side. Its 5 kVrms reinforced isolation protects embedded MCUs from ground faults and high common-mode transients typical in power electronics enclosures. Automotive gateway modules and battery management systems also benefit from the device's fast propagation delay and compact 8-pin SOP footprint.

Frequently Asked Questions
What isolation voltage does XISO1044BDR provide, and is it sufficient for IEC 61800 industrial drive applications?
XISO1044BDR achieves 5 kVrms reinforced isolation, which exceeds the basic insulation requirement of most IEC 61800-series motor drive standards that typically specify 2.5 kVrms. Reinforced isolation eliminates the need for external isolation transformers in the CAN bus interface, simplifying drive designs and reducing the PCB footprint while maintaining safety compliance in 400 V to 600 V AC motor control systems.
Can XISO1044BDR handle CAN FD frame rates, and what maximum bit rate does it support?
XISO1044BDR supports CAN FD data-phase bit rates up to 5 Mbps with a propagation delay under 150 ns, fully compatible with the CAN FD physical layer specification. At 5 Mbps the maximum data throughput allows transferring a 64-byte CAN FD payload in approximately 100 µs, making it suitable for fast ECU networks and high-speed diagnostic communication over standard twisted-pair bus cables.
How compact is the XISO1044BDR package, and does the 8-pin SOP footprint fit on standard CAN node PCBs?
The 8-pin SOP package has a body width of approximately 3.9 mm and a standard 1.27 mm pitch, occupying about 20 mm² total. This standard SOP8 footprint is compatible with any CAN transceiver SOP8 land pattern, allowing direct drop-in replacement of non-isolated transceivers while adding 5 kVrms isolation with no additional board real estate for an isolator IC.
