BQ29723DSER

Battery Management Overview

The BQ29723DSER is a single-cell battery protection IC designed for lithium-ion and lithium-polymer batteries. It operates within an 8 V supply voltage range and features a low quiescent current of 4 uA. The device provides comprehensive fault protection including over-current, over/under-voltage, and short-circuit detection. It is housed in a compact WSON-6 (1.5x1.5 mm) package suitable for surface-mount installation.

Battery Management Feature Summary

• Integrated protection against over-current, over/under-voltage, and short circuits for single-cell lithium-based batteries
• Ultra-low quiescent current consumption to minimize standby power drain
• Compact WSON-6 package design optimized for space-constrained portable applications

Battery Management Applications

• Portable electronic devices requiring single-cell battery protection
• Lithium-ion and lithium-polymer battery pack management systems
• Consumer electronics with strict size and power constraints

Battery Management Procurement Notes

Verify the specific datasheet revision and product change notifications prior to procurement. Confirm that the WSON-6 footprint matches your PCB layout requirements. Ensure compatibility with your system's voltage levels and thermal management capabilities. Check for any regional distribution restrictions or RoHS compliance documentation updates.

Battery Management Selection Notes

Select this component when a single-cell lithium battery requires integrated protection without external sensing resistors. Consider the WSON-6 package size relative to available board space. Evaluate the 4 uA quiescent current against your system's sleep mode power budget. Ensure the operating temperature range meets your application environment.

Battery Management Part Context

This part belongs to the Texas Instruments BQ297xx series of battery protection ICs. These components are designed to replace discrete protection solutions by integrating multiple safety functions into a single small-footprint device. The series supports various lithium chemistries and offers different pin configurations for diverse application needs.

Battery Management Replacement Considerations

Compatible substitutes include BQ29701DSER, BQ29702DSET, BQ29707DSER, and BQ29732DSER. Verify pinout compatibility and specific fault threshold settings before substitution. Ensure the replacement part maintains the same package type and electrical characteristics.
