BQ24314DSGR

Product Overview

The Texas Instruments BQ24314DSGR is a surface-mount battery protection IC intended for lithium-ion battery systems. The device uses an 8-WFDFN exposed-pad package, also identified as an 8-WSON (2x2) package, and supports surface-mount assembly. Its function is battery protection, with protection coverage that includes over-current, over-temperature, and over/under-voltage conditions. The specified junction temperature operating range is 0°C to 125°C (TJ).

Key Features

• Battery protection function for lithium-ion battery applications
• Fault protection includes over-current, over-temperature, and over/under-voltage conditions
• Operating junction temperature range specified from 0°C to 125°C (TJ)
• 8-WFDFN exposed-pad package, 8-WSON (2x2) package, surface-mount type

Applications

• Lithium-ion battery pack protection for portable devices
• Battery protection within power management subsystems
• Lithium-ion battery safety circuits in embedded systems

Design & Procurement Notes

Design and procurement considerations should focus on matching the device to lithium-ion battery protection requirements and on implementing the 8-WFDFN exposed-pad package correctly. The 8-WSON (2x2) surface-mount package affects PCB land pattern, component placement, and thermal relief, so the exposed pad should be incorporated into the layout with attention to soldering and heat dissipation. The specified 0°C to 125°C (TJ) operating range requires verification of junction temperature under expected load and environmental conditions. The over-current, over-temperature, and over/under-voltage fault protection functions should be mapped to the system's safety architecture, while circuit-level protection parameters should be confirmed from device documentation before finalizing the design. The part number BQ24314DSGR should be checked against the selected package and mounting method during procurement.
