MAX14690AEWX+T

Overview

The MAX14690AEWX+T is a wearable charge management solution designed for low-power applications. It integrates a linear battery charger, smart power selector, two ultra-low power buck regulators, and three ultra-low power LDOs. The device supports lithium-ion batteries with an operating supply voltage range of 2.7 V to 5.5 V. Output voltages are configurable from 800 mV to 1.8 V and 1.5 V to 3.3 V, delivering up to 200 mA output current. It operates within a temperature range of -40°C to +85°C in a WLP-36 package.

Feature Summary

• Integrates linear battery charger with smart power selector
• Includes two ultra-low power buck regulators
• Features three ultra-low power LDO linear regulators

Applications

• Low-power wearable electronic devices
• Small lithium-ion battery systems
• Portable consumer electronics requiring efficient power management

Procurement Notes

Verify the specific suffix (AEWX) against official Analog Devices documentation to confirm pinout and functional variations. Ensure compatibility with WLP-36 packaging requirements during PCB layout. Confirm RoHS compliance status through manufacturer certificates. Validate thermal performance specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring integrated charging and regulation in minimal space. The ultra-low quiescent currents of the integrated regulators make it suitable for battery-operated wearables. Consider the WLP-36 package constraints for board real estate. Verify input voltage ranges match the system's power source capabilities.

Part Context

This part belongs to the MAX14690 series of wearable charge management solutions. It consolidates multiple power management functions into a single compact package. The series targets applications where size and efficiency are critical. Other variants may offer different regulatory configurations or pinouts.

Replacement Considerations

Check for direct substitutes like MAX14690HEWX+T or MAX14690NEWX+T. Verify pin-to-pin compatibility and electrical parameter equivalence. Review updated datasheets for any functional changes in newer revisions.
