ZXCT181QA3W6-7

Overview

The ZXCT181QA3W6-7 is a current monitor and power regulator manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7 V to 5.5 V and draws a typical supply current of 300 uA. The device supports both high-side and low-side sensing configurations. It features a common-mode voltage output interface and provides an output current capability of 8 mA. The component is designed for operation across an extended temperature range from -40°C to +125°C. It is housed in a compact SOT-26-6 surface-mount package, suitable for space-constrained applications requiring precise current monitoring.

Feature Summary

• Supports flexible high-side or low-side current sensing configurations
• Provides a common-mode voltage output signal proportional to monitored current
• Operates with low quiescent supply current for energy-efficient designs
• Engineered for reliable performance across wide industrial temperature ranges

Applications

• Battery management systems for portable electronics
• Overcurrent protection circuits in consumer devices
• Power regulation monitoring in automotive subsystems
• Current limiting in industrial control equipment

Procurement Notes

Verify the specific suffix 'A3' against official Diodes Incorporated documentation to confirm the exact gain setting and pinout configuration required for your design. Ensure the SOT-26-6 footprint matches your PCB layout constraints. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed-gain current monitor is needed within a 2.7 V to 5.5 V supply range. The 8 mA output drive capability allows direct interfacing with ADCs or comparators without additional buffering. Consider the SOT-26-6 package size relative to available board space. Verify that the common-mode output requirement aligns with downstream signal conditioning circuitry capabilities.

Part Context

This part belongs to the ZXCT181Q series of current monitors from Diodes Incorporated. The series includes variants with different gain settings and accuracy levels. The 'Q' designation typically indicates automotive-grade qualification standards. The ZXCT181 family focuses on providing accurate current sensing solutions in compact packages for modern power management applications.

Replacement Considerations

Check Diodes Incorporated datasheets for ZXCT181A3W6-7 or ZXCT181QA4W6-7 as potential functional equivalents with similar gain characteristics. Verify pin compatibility and electrical specifications before substitution.
