ZXCT180B4W5-7

Overview

The ZXCT180B4W5-7 is a unidirectional current shunt monitor manufactured by Diodes Incorporated. It supports high-side and low-side sensing with a supply voltage range of 2.7 V to 5.5 V. The device operates within a temperature range of -40°C to +125°C and draws a typical operating supply current of 370 µA. It features an SOT-25-5 surface-mount package and provides a CM voltage output. This component is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Supports both high-side and low-side current sensing configurations
• Qualified for automotive environments under AEC-Q100 standards
• Provides common-mode voltage output for interface compatibility

Applications

• Automotive power rail monitoring
• Industrial power management systems
• Battery management circuits

Procurement Notes

Verify the specific suffix B4W5-7 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOT-25-5 package dimensions align with your PCB footprint. Confirm AEC-Q100 qualification status if deploying in automotive-grade assemblies, as this impacts long-term reliability expectations.

Selection Notes

Select this component when designing systems requiring precise current monitoring in automotive or industrial sectors. It is suitable for applications needing high-side or low-side sensing with a maximum supply voltage of 5.5 V. Consider the 370 µA quiescent current for battery-powered designs. Verify that the CM voltage output interface matches your downstream ADC or microcontroller input requirements.

Part Context

This part belongs to the ZXCT180 series of current monitors from Diodes Incorporated. It is designed for power management ICs (PMIC) applications. The series includes variants with different packages and outputs, but this specific model uses the SOT-25-5 package. It serves as a specialized solution for monitoring current flow in regulated power supplies.

Replacement Considerations

Check for other ZXCT180 series variants with compatible pinouts if space constraints change. Verify equivalent parts from other manufacturers only if they explicitly meet the AEC-Q100 qualification and 5.5 V max supply voltage limits.
