MAX17043G-E+U

Overview

The MAX17043G-E+U is a host-side fuel gauge for single-cell lithium-ion batteries. It utilizes the ModelGauge m5 algorithm to track relative state-of-charge without requiring battery relearn cycles or external current-sense resistors. The device operates within a supply voltage range of 2.5 V to 4.5 V and features a TDFN-8 package. It supports I²C communication at speeds up to 400 kHz, with a fixed 7-bit address of 0x6D. Key electrical parameters include a maximum operating temperature of +70°C and a minimum of -20°C.

Procurement Notes

Verify the specific suffix 'E' against official Analog Devices documentation to confirm environmental rating or tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TDFN-8 package. Confirm that the I²C interface requirements align with the host microcontroller capabilities. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when precise state-of-charge tracking is required for single-cell lithium-ion applications without adding external sense resistors. The ModelGauge m5 technology provides accurate capacity estimation across varying charge/discharge profiles. Consider the TDFN-8 package size for space-constrained portable designs. Verify that the operating temperature range meets the specific application environment requirements.

Part Context

The MAX17043 belongs to Maxim Integrated's fuel gauge family designed for portable electronics. It integrates advanced battery modeling algorithms into a compact footprint. The device simplifies system design by removing the need for complex calibration routines typically associated with coulomb counting methods. It serves as a cost-effective solution for managing battery life in consumer and industrial handheld devices.

Replacement Considerations

The MAX17044 is a compatible alternative for dual-cell (2S) lithium-ion pack applications. Both devices share similar algorithmic features and communication interfaces. Ensure that the target application requires single-cell monitoring rather than dual-cell support when selecting between these variants.
