ZXCT1085QE5TA

Overview

The ZXCT1085QE5TA is a high-side current monitor and power regulator from Diodes Incorporated, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 2.7 V to 40 V and supports input voltages up to 60 V. The device features a low quiescent current of 600 nA and utilizes an SOT-25-5 surface-mount package. It functions effectively across an extended temperature range from -40°C to +125°C, providing reliable monitoring capabilities for power management systems.

Feature Summary

• High-side current sensing capability for accurate power monitoring
• Automotive-grade reliability certified under AEC-Q100 standards
• Ultra-low static current consumption for energy efficiency
• Extended industrial and automotive temperature operation range

Applications

• Automotive battery monitoring systems
• Power distribution unit current sensing
• IoT board power consumption monitoring
• General DC power supply regulation

Procurement Notes

Verify the specific suffix E5TA corresponds to the required SOT-25 packaging and reel configuration. Confirm AEC-Q100 certification status if automotive compliance is mandatory. Ensure the 40 V maximum supply voltage aligns with system requirements rather than the 60 V absolute maximum rating. Check RoHS3 compliance documentation for environmental regulations.

Selection Notes

Select this component when high-side monitoring in automotive environments is required. The 40 V operating limit distinguishes it from higher voltage variants. Consider the SOT-25 footprint for space-constrained PCB layouts. Evaluate the 600 nA quiescent current against standby power budgets. Verify compatibility with external shunt resistors for desired current ranges.

Part Context

This part belongs to the ZXCT108x series of current monitors by Diodes Incorporated. It shares functional similarities with the ZXCT1082 and ZXCT1083 but differs in specific voltage ratings and accuracy specifications. The series targets PMIC applications requiring precise current measurement in compact packages.

Replacement Considerations

ZXCT1082QE5TA offers similar functionality with potentially different accuracy grades. ZXCT1083QE5TA provides comparable high-side monitoring within a 40 V limit. Verify pinout compatibility and thermal performance before substituting.
