Overview
The MAX17043G-E+T is a host-side fuel gauge for single-cell lithium-ion batteries. It utilizes the ModelGauge algorithm to track relative state-of-charge without external current-sense resistors or relearn cycles. The device operates on a 2.5V to 4.5V supply with 50µA operating current. It features ±12.5mV voltage accuracy up to 5.00V and provides low-battery alerts via an I²C interface in a compact TDFN-8 package.
Feature Summary
- Host-side fuel gauging for single-cell lithium-ion batteries
- ModelGauge algorithm eliminates need for battery relearn cycles
- No external current-sense resistor required
- Low-battery alert capability
Applications
- Smartphones
- Tablets
- Health and fitness monitors
- Digital still, video, and action cameras
- Medical devices
Procurement Notes
Verify component authenticity through authorized Analog Devices channels. Confirm RoHS compliance status and lead-free packaging specifications against the official datasheet. Ensure the ordering suffix matches the required tape-and-reel configuration for automated assembly processes.
Selection Notes
Select this component for applications requiring accurate SOC estimation without complex calibration. Suitable for space-constrained portable electronics where eliminating external sense resistors reduces BOM cost. Verify compatibility with the specific lithium cell chemistry and operating temperature range of the target system.
Part Context
