ZXCT1009QFTA

Overview

The ZXCT1009QFTA is a high-side current monitor from Diodes Incorporated, designed for automotive applications with AEC-Q100 qualification. It operates on a supply voltage range of 2.5 V to 20 V while consuming only 4 uA of quiescent current. The device provides an output voltage proportional to the sensed current with an accuracy of 2.5%. It supports a maximum input voltage of 2500 mV across the sense resistor and functions within a temperature range of -40 C to +85 C.

Feature Summary

• High-side current sensing capability
• Automotive grade reliability certification
• Ultra-low power consumption design

Applications

• Automotive battery monitoring systems
• Current limiting protection circuits
• Power management unit regulation

Procurement Notes

Verify the specific suffix QFTA against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 requirements for your target automotive application environment. Cross-reference the datasheet revision date to validate parameter consistency before integration into final designs.

Selection Notes

Select this component when high-side monitoring is required in space-constrained automotive modules. The low quiescent current makes it suitable for always-on circuits where battery drain must be minimized. Verify that the maximum input voltage and accuracy specifications align with the system's signal conditioning requirements.
