Overview
The ZXCT1107SA-7 is a high-side current monitor from the ZXCT11 series by Diodes Incorporated, designed for automotive applications with AEC-Q100 qualification. It operates within an input voltage range of 2.5 V to 36 V and features a low quiescent supply current of 19 nA. The device provides a proportional output current of 2.015 mA with an accuracy of 6%. It functions in temperatures from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- High-side current sensing capability for monitoring load currents
- Ultra-low power consumption suitable for battery-operated systems
- Automotive-grade reliability certified under AEC-Q100 standards
Applications
- Battery management systems in electric vehicles
- Current monitoring in automotive lighting circuits
- Power distribution unit protection
Procurement Notes
Verify the specific suffix 'SA' against the manufacturer's official datasheet to confirm the exact output current specification, as variations exist within the ZXCT11 family. Ensure the component meets the required AEC-Q100 grade for your target application. Cross-reference the SOT-23-3 package dimensions with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when high-side monitoring is required with minimal power overhead. The 2.015 mA output current allows for direct interfacing with ADCs or comparators without additional amplification stages. Consider the 6% accuracy tolerance relative to system precision needs. The wide operating temperature range supports deployment in harsh automotive environments.
Part Context
This part belongs to the ZXCT11 series of MicPWR current monitors. It shares the same core architecture and packaging as other variants like the ZXCT1107QSA-7 but differs in specific electrical characteristics such as output current scaling. The series is optimized for low-power automotive and industrial monitoring tasks requiring high-side configuration.
Replacement Considerations
Direct substitutes include other ZXCT1107 variants with matching output currents. Verify pin compatibility and thermal performance when replacing with generic high-side current sensors. Ensure any alternative maintains AEC-Q100 certification if used in automotive contexts.
