Battery Management datasheet and documents for BQ29312PWRG4

BQ29312PWRG4

Battery Management Overview

The BQ29312PWRG4 is a battery protection analog front end (AFE) designed for two, three, and four-cell lithium-ion or lithium-polymer battery packs. It operates within a supply voltage range of 4 V to 25 V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 24-pin TSSOP package.

Battery Management Feature Summary

Provides high-voltage interface and primary protection for multi-cell lithium-based battery packs
Integrates a low-dropout amplifier for system power management
Enables accurate state-of-charge calculations through cell impedance measurement capabilities

Battery Management Applications

Portable electronic devices requiring multi-cell battery protection
Smart-battery fuel gauge systems utilizing Impedance Track technology
Lithium-ion and lithium-polymer battery pack management subsystems

Battery Management Procurement Notes

Verify the exact suffix against manufacturer documentation to confirm package type and environmental compliance. Ensure the component matches the specific cell count requirements of your design. Cross-reference the datasheet revision to confirm pinout compatibility with existing layouts.

Battery Management Selection Notes

Select this component when designing protection circuits for two to four series-connected cells. It serves as the companion AFE for gas gauges like the bq20z80. Verify that the system requires the integrated LDO amplifier functionality before finalizing the selection.

Battery Management Part Context

This part belongs to the BQ29312 family of battery protection AFEs from Texas Instruments. Variants such as BQ29312APWR and BQ29312RGE offer similar protection functions but differ in package styles, including TSSOP and VQFN options. The family is designed for integration with smart-battery gas gauging solutions.

Battery Management Replacement Considerations

BQ29312APWR and BQ29312APWRG4 are functionally equivalent alternatives in the same TSSOP-24 package. Verify pin-to-pin compatibility and electrical specifications before substitution.
