Overview
The ZXCT1110QW5-7 is a high-side current monitor manufactured by Diodes Incorporated, designed for automotive applications. It operates within an input voltage range of 2.5 V to 36 V and features a low quiescent current of 19 nA. The device provides a proportional output current of 3 µA with an accuracy of 6%. It is qualified to AEC-Q100 standards and functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a compact SOT-25-5 surface-mount package.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Ultra-low power consumption suitable for battery monitoring
- High-side sensing capability for positive supply rails
Applications
- Battery management systems in automotive electronics
- Current monitoring in vehicle power distribution networks
- Protection circuits in automotive control modules
Procurement Notes
Verify the specific suffix 'QW5' against official Diodes Incorporated documentation to confirm automotive grade status and pinout configuration. Ensure compatibility with your system's voltage levels and thermal requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when automotive reliability and ultra-low standby current are critical. The 3 µA output current allows for direct interfacing with ADCs or comparators without additional amplification. Consider the 6% accuracy tolerance against application requirements. The SOT-25-5 package offers space efficiency for dense PCB layouts.
Part Context
This part belongs to the ZXCT11xx series of current monitors from Diodes Incorporated. The series includes variants optimized for different accuracy levels and package types. The 'Q' prefix typically denotes automotive qualification, while 'W5' indicates the specific SOT-25-5 packaging format used in this model.
Replacement Considerations
Check Diodes Incorporated datasheets for direct replacements such as ZXCT1110W5-7 (non-automotive) or other ZXCT11xx variants. Verify that substitute parts meet AEC-Q100 requirements if automotive use is intended. Pin-to-pin compatibility must be confirmed via official cross-reference guides.
