Aipu Isolated Transceiver Modules

Integrated isolated transceivers offer significant advantages over discrete isolation solutions: 1) Simplified design - no need for separate isolation power supply, reducing component count and design complexity

2) Reduced PCB space - single compact module replaces transceiver, isolation barrier, and DC-DC converter

3) Guaranteed isolation performance - factory-tested and certified isolation voltage (2500VDC)

4) Better reliability - integrated design eliminates interconnection issues

5) Cost effective - typically lower total cost than discrete solution

6) Faster time-to-market - no isolation power supply design required. The integrated DC-DC converter generates isolated power internally, eliminating the need for external transformers or isolated DC-DC modules.

Use integrated isolated transceivers to simplify design, reduce PCB space, and lower total cost compared to discrete isolation solutions.

Select isolated transceiver based on your communication protocol: 1) CAN bus (CTM series): Use for Controller Area Network applications, automotive, industrial automation. Supports up to 1Mbps, multi-master bus, differential signaling with high noise immunity

2) RS-485 (RSM series): Use for long-distance differential communication, industrial networks, building automation. Supports up to 500Kbps, multi-drop capability (32-256 nodes), 1200m max distance

3) RS-232 (RSM232 series): Use for point-to-point serial communication, legacy equipment, short distances. Supports up to 115.2Kbps, single-ended signaling, 15m max distance. All three types provide 2500VDC isolation and integrated power. Match the transceiver type to your existing network protocol or system requirements.

Match transceiver to protocol: CTM for CAN bus, RSM for RS-485 networks, RSM232 for RS-232 serial links.

Aipu isolated transceivers provide 2500VDC galvanic isolation between logic side and bus side. This high isolation voltage effectively protects sensitive control electronics from ground loops, common-mode noise, and high-voltage faults on the bus side. The 2500VDC isolation level exceeds the requirements of most industrial and commercial applications. For medical equipment or high-voltage power system applications, this isolation level provides adequate safety margin. The isolation is factory-tested and certified, ensuring consistent performance and reliability.

2500VDC isolation suitable for industrial, commercial, and most medical applications. Provides excellent protection against ground loops and noise.

No, Aipu isolated transceivers do not require external isolation power supply. The modules integrate a DC-DC converter that generates isolated power internally from the logic side power supply (3.3V or 5V). This integrated power supply eliminates the need for external isolation transformers, separate DC-DC modules, or complex power supply design. Simply connect the logic side power and ground, and the module automatically generates isolated power for the bus side transceiver. This significantly simplifies design, reduces PCB space, lowers BOM cost, and improves reliability compared to discrete isolation solutions.

No external isolation power needed - integrated DC-DC converter generates isolated power internally. Just connect logic side power.

Aipu isolated transceivers include comprehensive protection features: 1) 2500VDC galvanic isolation: Protects logic side from high-voltage faults and noise on bus side

2) ESD protection: HBM 4kV protection on bus pins against electrostatic discharge

3) Bus fault protection: Withstands continuous voltage faults on bus pins without damage

4) Thermal shutdown: Disables output if internal temperature exceeds safe limits

5) Short circuit protection: Limits current during bus short circuits

6) Power-on reset: Ensures defined startup state. These protections make the transceivers suitable for harsh industrial environments where wiring faults, ESD events, and electrical noise are common.

Comprehensive protection including 2500VDC isolation, 4kV ESD, bus fault protection for reliable operation in harsh environments.
