MAX17044 - Low-Cost 1S/2S Fuel Gauges

Download the MAX17044 datasheet PDF. This datasheet also covers the MAX17043 variant, as both devices belong to the same low-cost 1s/2s fuel gauges family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX17043/MAX17044 are ultra-compact, low-cost, host-side fuel-gauge systems for lithium-ion (Li+) batteries in handheld and portable equipment.

The MAX17043 is configured to operate with a single lithium cell and the MAX17044 is configured for a dual-cell 2S pack.

Key Features

  • Host-Side or Battery-Side Fuel Gauging 1 Cell (MAX17043) 2 Cell (MAX17044).
  • Precision Voltage Measurement ±12.5mV Accuracy to 5.00V (MAX17043) ±30mV Accuracy to 10.00V (MAX17044).
  • Accurate Relative Capacity (RSOC) Calculated from ModelGauge Algorithm.
  • No Offset Accumulation on Measurement No Full-to-Empty Battery Relearning Necessary No Sense Resistor Required External Alarm/Interrupt for Low-Battery Warning 2-Wire Inte.

19-4811; Rev 1; 4/10 www.DataSheet4U.com KIT ATION EVALU E L B AVAILA Compact, Low-Cost 1S/2S Fuel Gauges with Low-Battery Alert General Description The MAX17043/MAX17044 are ultra-compact, low-cost, host-side fuel-gauge systems for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17043 is configured to operate with a single lithium cell and the MAX17044 is configured for a dual-cell 2S pack. The MAX17043/MAX17044 use a sophisticated Li+ battery-modeling scheme, called ModelGauge™ to track the battery’s relative state-of-charge (SOC) continuously over a widely varying charge/discharge profile. Unlike traditional fuel gauges, the ModelGauge algorithm eliminates the need for battery relearn cycles and an external current-sense resistor.
