IL015E

Overview

The IL015E is a low-power Tunnel Magnetoresistance (TMR) digital isolator from NVE, featuring four channels in a 16-SOIC package. It supports data rates up to 110 Mbps with propagation delays as low as 4 ns. The device operates on a single supply voltage ranging from 2.7V to 5.5V and provides isolation voltages of 2.5 kVrms or 3.75 kVpeak. Designed for high reliability, it offers common-mode transient immunity exceeding 100 kV/µs and functions across an extended temperature range of -40°C to +125°C.

Feature Summary

• Utilizes proprietary Tunnel Magnetoresistance (TMR) technology for robust signal transmission without magnetic field interference.
• Provides high-speed data isolation with low power consumption suitable for battery-operated systems.
• Features exceptional common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing reliable patient isolation barriers
• Automotive electronic control units (ECUs) operating in harsh electromagnetic environments

Procurement Notes

Verify the specific isolation rating (2.5 kVrms vs 3.75 kVpeak) required for your application against the datasheet specifications. Confirm that the 16-SOIC package dimensions align with your PCB footprint constraints. Ensure the selected variant meets the necessary regulatory certifications such as UL or IEC standards for your target market compliance requirements.

Selection Notes

Select the IL015E when four isolated channels are needed within a compact surface-mount footprint. Consider this component for designs prioritizing low power consumption alongside high-speed data transfer capabilities. Evaluate the thermal performance requirements to ensure operation within the specified -40°C to +125°C range under your system's load conditions.

Part Context

The IL015E belongs to NVE’s IsoLoop family of TMR isolators, which leverage giant magnetoresistive sensor technology. This series replaces traditional optical or capacitive isolators by offering superior stability and lower power usage. The four-channel configuration allows for complex bus isolation in a single package, simplifying board layout compared to discrete solutions.

Replacement Considerations

Direct replacements include other NVE IL01x series variants like the IL011-3E or IL015E derivatives if channel count differs. Cross-brand alternatives may require significant redesign due to differing interface characteristics and pinouts. Verify compatibility with existing logic levels and supply voltages before substituting.
