ZXCT1087E5TA

Overview

The ZXCT1087E5TA is a high-side current monitor and regulator integrated circuit manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7 V to 40 V and supports surface-mount installation in a SOT-25 package. The device functions as a precision current sensing solution with a quiescent supply current of 600 nA. It is designed for automotive-grade applications, certified under AEC-Q100 standards, and maintains reliable operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• High-side current monitoring capability for accurate load current sensing
• Ultra-low quiescent supply current for efficient power management
• Automotive-grade reliability with AEC-Q100 certification
• Extended industrial temperature range operation

Applications

• Automotive battery monitoring systems
• High-side load switching protection circuits
• Current limiting in automotive power distribution units
• Battery management system (BMS) current sensing

Procurement Notes

Verify the specific suffix E5TA corresponds to the standard reel packaging configuration when ordering. Confirm that the application environment remains within the specified 2.7 V to 40 V input voltage limits. Ensure thermal management strategies account for the maximum operating junction temperature. Check for any recent Product Change Notifications regarding leadframe materials or bond wire composition updates prior to final design approval.

Selection Notes

Select this component when high-side sensing is required with minimal static power consumption. The SOT-25 package offers a compact footprint suitable for space-constrained automotive PCB layouts. Consider the 40 V maximum input rating against potential transient voltage spikes in the target power rail. The AEC-Q100 qualification ensures suitability for rigorous automotive environmental stress testing requirements.

Part Context

This part belongs to the ZXCT108x series of current monitors from Diodes Incorporated. The series provides various accuracy and voltage rating options for different automotive and industrial applications. The ZXCT1087 variant specifically targets high-voltage high-side monitoring scenarios requiring low standby current consumption.

Replacement Considerations

The ZXCT1083E5TA serves as a functional substitute within the same family, offering similar high-side monitoring capabilities but with a lower maximum input voltage rating of 40 V compared to other variants in the broader series.
