MAX17116ETG+

Overview

The MAX17116ETG+ is a specialized power management IC designed for single-cell lithium-ion battery applications. It integrates two independent regulated outputs providing +4.6V and -4.9V from an input voltage range of 2.3V to 4.2V. The device operates with a maximum supply current of 90 uA and functions within a temperature range of -40°C to +85°C. Housed in a compact 24-TQFN (4x4) package with an exposed pad, it facilitates efficient asymmetric power conversion for mixed-signal systems requiring negative supplies.

Feature Summary

• Provides dual asymmetric regulated outputs (+4.6V and -4.9V) from a single-cell input
• Optimized for low-power operation in mixed-signal environments
• Integrated thermal performance via exposed pad TQFN package

Applications

• Mixed-signal circuitry requiring negative analog supplies
• Single-cell lithium-ion battery powered devices
• Portable electronics with asymmetric power requirements

Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm the specific suffix ETG+ matches the required 24-TQFN package and RoHS compliance status. Check for end-of-life or obsolescence notices as availability may be limited. Ensure thermal design accounts for the exposed pad requirement on the PCB ground plane.

Selection Notes

Select this component when asymmetric positive and negative rails are needed from a single lithium cell. The fixed output voltages simplify design compared to adjustable regulators. Consider the 90 uA quiescent current for battery life calculations. The TQFN-24 package requires adequate copper area for heat dissipation during continuous operation.

Part Context

This part belongs to the Maxim Integrated PMIC family focused on portable power solutions. It addresses the need for stable negative voltages in single-supply systems without external inductors. The device complements other Maxim battery management components by handling specific analog supply needs efficiently.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts if considering alternative asymmetric regulators.
