MAX14690NEWX+T

Overview

The MAX14690NEWX+T is a wearable charge management solution designed for low-power applications. It integrates a linear battery charger with an intelligent power selector and optimized peripherals. The device features two ultra-low power buck regulators with typical static currents of 900nA, and three ultra-low power LDO linear regulators with typical static currents of 600nA. It supports lithium-ion batteries, operates on supply voltages from 2.7V to 5.5V, and provides output voltages ranging from 800mV to 1.8V and 1.5V to 3.3V at up to 200mA. It is housed in a WLP-36 package.

Feature Summary

• Integrates a linear battery charger with intelligent power selection for seamless source switching.
• Includes two ultra-low power buck regulators optimized for minimal quiescent current consumption.
• Features three ultra-low power LDO linear regulators to support diverse peripheral voltage requirements.

Applications

• Low-power wearable electronic devices
• Small lithium-ion battery systems
• Wearable health monitoring equipment

Procurement Notes

Verify the specific suffix 'NEWX' against official Analog Devices documentation to confirm pinout and functional compatibility. Check current availability status as distribution may be limited. Ensure the WLP-36 package dimensions align with your PCB footprint design constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing compact wearable systems requiring integrated charging and multiple regulated rails. The ultra-low quiescent currents of the integrated buck and LDO regulators make it suitable for battery-operated devices where standby power conservation is critical. Verify that the input voltage range matches your system's power source capabilities.

Part Context

This part belongs to the MAX14690 series of wearable charge management solutions from Analog Devices (formerly Maxim Integrated). The series is engineered specifically for space-constrained portable electronics, combining power management and battery charging functions into a single small-footprint integrated circuit to reduce overall system complexity.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers within the MAX14690 family. Ensure any substitute maintains the same WLP-36 package and electrical specifications for direct compatibility.
