MAX77654NENV+T

Power Management - Specialized Overview

The MAX77654NENV+T is an ultra-low power Power Management IC (PMIC) from Analog Devices/Maxim Integrated. It integrates a battery charger and three-output Single Inductor Multiple Output (SIMO) DC-DC converter. The device supports input voltages of 4.25V to 5.5V and provides regulated outputs for system power management. It features a dedicated Li-Ion/Li-Po charger with programmable charge current and termination voltage. The SIMO section includes two buck converters and one LDO, designed for high efficiency in space-constrained portable applications.

Power Management - Specialized Procurement Notes

Verify the complete part number including suffixes such as +T for reel packaging when ordering. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure compatibility with your specific voltage requirements and thermal conditions. Check for any recent lifecycle notices or obsolescence warnings directly from Analog Devices. Validate that the TDFN package dimensions match your PCB footprint design.

Power Management - Specialized Selection Notes

Select this PMIC for applications demanding minimal solution size and high efficiency. The SIMO topology reduces inductor count compared to multi-inductor designs. Consider the maximum load current requirements of each output rail against the device specifications. Evaluate the thermal performance within the intended enclosure. Verify that the I2C interface matches the host controller's capabilities.

Power Management - Specialized Part Context

The MAX77654 series belongs to Maxim Integrated's portfolio of ultra-low power PMICs. It is designed specifically for mobile and wearable markets where power efficiency and footprint are critical.
