Overview
The ZXCT181A1W6-7 is a current monitor and regulator manufactured by Diodes Incorporated, designed for high or low-side sensing applications. It operates within an input voltage range of 2.7 V to 5.5 V and consumes a typical supply current of 300 uA. The device provides an 8 mA output current capability and functions across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-26-6 surface-mount format, it supports cut tape, reel, and MouseReel packaging options with a standard factory quantity of 3000 units.
Feature Summary
- Supports both high-side and low-side current sensing configurations
- Provides common-mode voltage output for monitoring applications
- Operates with low quiescent current consumption
Applications
- Battery management systems
- Portable electronic devices
- Power management circuits
Procurement Notes
Verify the specific suffix A1W6-7 against official Diodes Incorporated documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before integration into regulated products.
Selection Notes
Select this component when a low-voltage, low-power current monitor is required for portable or battery-operated equipment. The SOT-26 package offers space efficiency for dense layouts. Consider the 300 uA supply current impact on overall system power budget during continuous operation phases.
Part Context
This part belongs to the ZXCT181 series of current monitors from Diodes Incorporated. It is categorized under PMIC - Power Management ICs. The series includes variants with different accuracy grades and output configurations, all sharing similar low-power operational characteristics suitable for modern mobile and consumer electronics.
Replacement Considerations
The INA181A2IDBVR is listed as a similar alternative by distributors, though it is an instrumentation amplifier rather than a dedicated current monitor. Verify functional equivalence carefully before substitution.
