ZXCT1082QE5TA

Overview

The ZXCT1082QE5TA is a high-side current monitor and regulator integrated circuit manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7V to 60V and features a typical quiescent supply current of 600nA. The device provides a current sensing accuracy of ±2% and is qualified to AEC-Q100 automotive standards. It is housed in a compact SOT-25 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• High-side current monitoring capability for positive rail applications
• Automotive-grade reliability with AEC-Q100 qualification
• Ultra-low power consumption suitable for battery-operated systems

Applications

• Battery management systems in electric vehicles
• Current limiting protection in automotive lighting circuits
• Power distribution unit monitoring in vehicle architectures

Procurement Notes

Verify the specific suffix E5TA against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure that the procurement channel provides traceability documentation required for automotive grade components. Confirm RoHS3 compliance status prior to finalizing orders to meet environmental regulations.

Selection Notes

Select this component when high-side sensing is required with strict accuracy constraints. The 60V maximum input rating accommodates standard automotive electrical systems. Consider the SOT-25 package dimensions for PCB layout constraints. Verify thermal performance requirements against the specified operating temperature range.

Part Context

This part belongs to the ZXCT108x series of current monitors, designed specifically for automotive and industrial power management applications. The series offers various voltage ratings and accuracy levels to suit different system requirements while maintaining consistent packaging and interface characteristics.

Replacement Considerations

ZXCT1083QE5TA: Offers 40V input rating instead of 60V. ZXCT1084QE5TA: Provides similar functionality with potentially different internal reference characteristics. Verify exact parameter matching before substitution.
