UCC5618QPTR

Overview

The UCC5618QPTR is an automotive-grade, dual-channel digital isolator manufactured by Texas Instruments. It provides bidirectional signal isolation with a maximum data rate of 150 Mbps per channel and supports a peak pulse width of 20 ns. The device operates within a wide supply voltage range of 3 V to 5.5 V for both the input and output sides. It features a high common-mode transient immunity (CMTI) of ±100 kV/μs and is designed for robust performance in harsh electromagnetic environments. The component is housed in a 16-pin TSSOP package and is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Dual-channel bidirectional digital isolation for independent signal transmission
• High common-mode transient immunity ensuring reliable operation in noisy environments
• Automotive qualification compliant with AEC-Q100 standards for durability
• Wide operating supply voltage range supporting diverse system architectures

Applications

• Automotive gate driver interfaces for motor control systems

Procurement Notes

Verify the specific suffix 'QPTR' corresponds to the required tape-and-reel packaging configuration and temperature grade. Confirm that the AEC-Q100 qualification status meets the specific reliability requirements of the target automotive application before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel isolation is required for automotive gate driving or high-speed digital communication. Ensure the system's common-mode noise levels remain below the specified 100 kV/μs limit. Verify that the 150 Mbps data rate aligns with the timing requirements of the controlled signals.

Part Context

This part belongs to the UCC561x family of automotive digital isolators from Texas Instruments. These devices are engineered to replace traditional magnetic couplers in automotive systems, offering higher integration and improved reliability. The family includes variants with different channel counts and data rates tailored for various automotive networking and control needs.

Replacement Considerations

Check for direct pin-compatible alternatives within the UCC561x series that may offer updated packaging or slightly different speed grades. Verify that any substitute maintains the same AEC-Q100 qualification level and CMTI specifications to ensure functional equivalence in automotive designs.
