Valid for logic state as described or open circuit X = don’t care Features • Single-chip isolated CAN/DeviceNet transceiver • Fully compliant with the ISO 11898 CAN standard • Best-in-class loop delay (180 ns) • 3.0 V to 5.5 V input power supplies • >110-node fan-out • High speed (up to 1 Mbps) • 2,500 V RMS isolation (1 minute) • Very low Electromagnetic Emission (EME) • Differential signaling for excellent Electromagnetic Immunity (EMI) • 30 kV/µs transient immunity • Silent mode to disable transmitter • Unpowered nodes do not disturb the bus • Transmit data (TxD) dominant time-out function • Edge triggered, non-volatile input improves noise performance • Bus pin transient protection for automotive environment • Thermal shutdown protection • Short-circuit protection for ground and bus power • −55°C to +125°C operating temperature • 0.15" and 0.3" and 16-pin JEDEC-standard SOIC packages • UL1577 and IEC 61010-2001 approved Applications • Noise-critical CAN • Partially-powered CAN • DeviceNet • Factory automation Description The IL41050 is a galvanically isolated, high-speed CAN (Controller Area Network) transceiver, designed as the interface between the CAN protocol controller and the physical bus. The IL41050 provides isolated differential transmit capability to the bus and isolated differential receive capability to the CAN controller via NVE’s patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology. Advanced features facilitate reliable bus operation. Unpowered nodes do not disturb the bus, and a unique non-volatile programmable power-up feature prevents unstable nodes. The devices also have a hardware-selectable silent mode that disables the transmitter. Designed for harsh CAN and DeviceNet environments, IL41050T transceivers have transmit data dominant time-out, bus pin transient protection, thermal shutdown protection, and short-circuit protection, Unique edge-triggered inputs improve noise performance. Unlike optocouplers or other isolation technologies, IsoLoop isolators have indefinite life at high voltage. |
