Overview
The ZXCT1086QE5TA is an automotive-grade high-side current monitor and power regulator manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 60 V, featuring a maximum common-mode voltage of 60 V. The device draws a typical operating supply current of 25 µA and has a quiescent current of 600 nA. It is qualified under AEC-Q100 standards for automotive applications. The component is housed in a compact SOT-25-5 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- High-side current sensing capability with integrated regulation functions
- Automotive qualification compliant with AEC-Q100 reliability standards
- Ultra-low quiescent current consumption for energy-efficient operation
- Wide input voltage range supporting high common-mode environments
Applications
- Automotive battery monitoring systems
- High-side load switching protection circuits
- Current limiting in automotive power distribution units
- Power management in electric vehicle subsystems
Procurement Notes
Verify the specific suffix E5TA corresponds to the required tape-and-reel packaging configuration. Confirm that the AEC-Q100 grade meets the target automotive application's thermal and reliability requirements. Ensure the 60V common-mode rating aligns with the system's maximum bus voltage. Check for any recent product change notifications regarding leadframe materials or bond wire composition that may affect long-term sourcing stability.
Selection Notes
Select this component when high-side monitoring is required in automotive environments with voltages up to 60V. The low 25µA supply current makes it suitable for always-on battery monitoring applications where standby power is critical. Compare against lower-voltage variants like the ZXCT1083 if the system voltage does not exceed 40V. Consider the SOT-25-5 footprint constraints during PCB layout design.
Part Context
This part belongs to the ZXCT108x series of high-side current monitors from Diodes Incorporated. It shares architectural similarities with the ZXCT1082 and ZXCT1083 but offers an extended 60V common-mode voltage rating. The series is designed for robust performance in noisy automotive electrical environments, providing accurate current sensing and power regulation capabilities.
Replacement Considerations
ZXCT1083QE5TA (Lower voltage rating)
