MAX20335GEWX+T

Power Management - Specialized Overview

The MAX20335GEWX+T is a specialized Power Management IC (PMIC) designed for wearable and IoT applications. It integrates a linear battery charger with intelligent power path management, an ultra-low IQ LDO regulator, and multiple peripheral interfaces including I2C, GPIOs, and a real-time clock. The device operates within an input voltage range of 1.71 V to 5.5 V and supports output voltages from 700 mV to 4 V. It features a maximum output current of 500 mA and dissipates up to 1.74 W of power. The component is housed in a compact 36-ball Wafer Level Package (WLP-36) measuring 2.69 x 2.44 mm, suitable for space-constrained designs.

Power Management - Specialized Procurement Notes

Verify availability status carefully, as the MAX20335GEWX+T may be subject to limited supply or discontinuation notices depending on the region and distributor. Confirm the specific suffix 'GEWX' matches the required package and temperature grade. Cross-reference with the official Analog Devices datasheet revision history to ensure compliance with current manufacturing standards before finalizing procurement plans.

Power Management - Specialized Selection Notes

Select this PMIC when designing for ultra-low power consumption in wearable form factors. It is appropriate for single-cell lithium-ion or lithium-polymer battery systems requiring integrated charging and regulation. Ensure the design accommodates the 36-ball WLP package constraints and thermal dissipation requirements given the 1.74 W power handling capability.

Power Management - Specialized Part Context

This component belongs to the MAX20335 family of power management solutions. It serves as a comprehensive charge management solution for small lithium-ion systems. The GEWX variant specifically denotes the WLP-36 package configuration. It replaces older discrete power management architectures by consolidating charging, regulation, and control functions into a single compact integrated circuit.

Power Management - Specialized Replacement Considerations

The MAX20335AEWX+ is a related part within the same series but has been marked as discontinued. Verify if the AEWX+ variant is available as a substitute, noting potential differences in production status. No other direct cross-model substitutes are confirmed in public documentation without further engineering validation.
