LTC2941IDCB-1#TRMPBF

Battery Management Overview

The LTC2941IDCB-1#TRMPBF is a battery gas gauge integrated circuit designed for single-cell lithium-ion or lithium-polymer batteries. It utilizes an I2C interface to provide accurate state-of-charge information by measuring current and voltage. The device operates within a temperature range of -40°C to +85°C and is housed in a compact 6-WFDFN (2x3 mm) package with an exposed pad.

Battery Management Feature Summary

• Provides digital state-of-charge data via standard I2C communication
• Integrates precision current and voltage measurement capabilities
• Supports calibration for improved accuracy across varying conditions

Battery Management Applications

• Portable electronic devices requiring precise battery monitoring
• Medical equipment needing reliable power status indication

Battery Management Procurement Notes

Verify the specific suffix '-1' indicates the fixed threshold configuration if required by your design, as variants exist. Confirm the 'PBF' designation ensures lead-free compliance. Check current availability status as this component family has faced end-of-life notifications for certain packages. Ensure your PCB footprint matches the 6-WFDFN specification with appropriate thermal relief for the exposed pad.

Battery Management Selection Notes

Select this part when high accuracy state-of-charge reporting is critical for single-cell applications. It is suitable for designs where I2C connectivity is preferred over analog outputs. Consider the operating temperature range and package size constraints. Evaluate if the integrated measurement features meet your system's power management requirements without external sensing components.
