ZXCT1080QE5TA

Overview

The ZXCT1080QE5TA is an automotive-grade high-side current monitor manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 60 V and features a quiescent current of 30 µA. The device provides a voltage output proportional to the sensed current, with a typical bandwidth of 0.5 MHz. It is designed for precise current sensing in power management applications, offering high common-mode rejection capabilities. The component is qualified under AEC-Q100 standards and is housed in a compact SOT-25-5 surface-mount package suitable for space-constrained designs.

Feature Summary

• High-side current sensing capability for accurate monitoring
• Automotive qualification ensuring reliability in harsh environments
• Low quiescent current consumption for energy efficiency
• Wide input voltage range supporting various power rails

Applications

• Battery management systems in electric vehicles
• Power distribution units in automotive electronics
• Current limiting protection circuits
• Load switching control applications

Procurement Notes

Verify the specific suffix E5TA corresponds to the required packaging format, such as cut tape or reel, as ordering suffixes may affect logistics but not electrical function. Confirm AEC-Q100 compliance requirements match your system specifications. Ensure the 60 V maximum rating aligns with your circuit's peak voltage conditions. Check for any recent product change notices regarding lead frame materials or bond wire composition that might impact assembly processes.

Selection Notes

Select this component when high-side current monitoring is required in automotive environments with voltages up to 60 V. Consider the 30 µA quiescent current if power efficiency is critical. The SOT-25-5 package offers a small footprint compared to larger alternatives. Evaluate the 0.5 MHz bandwidth against your signal frequency needs. Compare with other ZXCT108x series parts if different voltage ratings or accuracy levels are needed.

Part Context

This part belongs to the ZXCT108x series of current monitors from Diodes Incorporated. The series includes variants with different voltage ratings, such as the ZXCT1082Q (60 V) and ZXCT1083Q (40 V). These devices share similar functional architectures but differ in maximum operating voltages and specific performance characteristics tailored for various automotive power management applications.

Replacement Considerations

ZXCT1082QE5TA is a verified substitute within the same series, offering compatible functionality with a 60 V rating.
