ZXCT181A3W6-7

Overview

The ZXCT181A3W6-7 is a current and power monitor manufactured by Diodes Incorporated, designed for high-side and low-side sensing applications. It operates within an input voltage range of 2.7V to 5.5V and features a common-mode voltage output in a compact SOT-26 package. The device provides an output current capability of 8mA and maintains a precision accuracy of ±1%. It is rated for operation across an extended temperature range from -40°C to +125°C (TA). This component belongs to the ZXCT181 series and is supplied in tape and reel packaging with a standard factory quantity of 3,000 units.

Feature Summary

• Supports both high-side and low-side current monitoring configurations
• Provides a common-mode voltage output signal proportional to sensed current
• Operates on single supply voltages ranging from 2.7V to 5.5V

Applications

• Battery management systems requiring precise current measurement
• Power supply monitoring in portable electronic devices
• Over-current protection circuits in industrial equipment

Procurement Notes

Verify the specific suffix W6-7 corresponds to the SOT-26 package and tape-and-reel configuration. Confirm that the A3 designation matches the required gain or accuracy specifications for the target design. Ensure compatibility with the 2.7V to 5.5V operating voltage range. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a small footprint SOT-26 package is required for current sensing. It is suitable for designs needing ±1% accuracy without external calibration. Consider the 8mA output drive capability for interfacing with ADCs or comparators. Evaluate the -40°C to +125°C temperature range against the operational environment requirements.

Part Context

This part is part of the ZXCT181 family of current monitors from Diodes Incorporated. It serves as a specialized PMIC solution for power management applications. The device integrates sensing elements to provide accurate current feedback in compact form factors suitable for space-constrained consumer and industrial electronics.
