ZXCT180B1W5-7

Overview

The ZXCT180B1W5-7 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 supports both high-side and low-side sensing configurations. The device features a typical supply current of 370 µA and delivers an output current capability of 8 mA. It is housed in a compact SOT-25-5 surface-mount package and is designed for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports flexible high-side or low-side current sensing applications
• Provides regulated CM voltage output for monitoring purposes
• Operates with low quiescent current consumption

Applications

• Battery management systems requiring current monitoring
• Power distribution units needing regulation
• Portable electronic devices with limited power budgets

Procurement Notes

Verify the specific suffix 'B1' against official Diodes Incorporated documentation to confirm the exact gain setting and tolerance, as these parameters define the functional performance. Ensure the SOT-25-5 package compatibility matches your PCB footprint requirements. Confirm that the 5.5 V maximum voltage rating aligns with your system's supply rails before finalizing procurement.

Selection Notes

Select this component when a low-voltage (up to 5.5 V) current monitor with integrated regulation is required. It is suitable for designs prioritizing low standby current and compact SMD packaging. Consider alternative models if higher voltage tolerance or different sensing accuracy specifications are necessary for the target application environment.

Part Context

This part belongs to the ZXCT180 series of current monitors from Diodes Incorporated. It shares the SOT-25-5 form factor with variants like the ZXCT180A1W5-7 but differs in internal gain settings defined by the 'B1' suffix. The series targets cost-sensitive, space-constrained power management applications in consumer and industrial electronics.

Replacement Considerations

The ZXCT180A1W5-7 is a related variant within the same series sharing the SOT-25-5 package and voltage range. Verify if the gain difference between the 'A1' and 'B1' suffixes impacts circuit functionality before substitution.
