BQ7791508PW

Battery Management Overview

The BQ7791508PW is a battery protection IC from Texas Instruments designed for 3-series to 5-series lithium-ion stacks. It operates within a supply voltage range of 3 V to 25 V and supports an output voltage of 16 V. The device features ultra-low quiescent current, with a typical operating supply current of 48 uA. It is housed in a TSSOP-24 package suitable for surface mount installation. The component functions as a primary protector with autonomous cell balancing capabilities and includes a HIBERNATE mode for extended standby life.

Battery Management Feature Summary

• Supports stackable configurations for 3-series to 5-series battery packs
• Integrates autonomous cell balancing functionality
• Includes HIBERNATE mode for low-power standby operation

Battery Management Applications

• Lithium-ion battery pack protection
• Portable electronic devices requiring multi-cell stacks
• Power tools with series-connected battery modules

Battery Management Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-24 tube packaging configuration when ordering. Confirm that the application design aligns with the 3-to-5-series stackable architecture supported by this part number. Ensure compatibility with the required 16 V output specification for the target system.

Battery Management Selection Notes

Select this component for applications requiring integrated protection and balancing in a single primary protector IC. The choice is driven by the need for ultra-low power consumption and support for multiple series cells without external balancing circuitry. Consider the TSSOP-24 package constraints and the specific voltage requirements of the battery stack.

Battery Management Part Context

This part belongs to the BQ77915 family of battery management ICs. It serves as a specialized solution for protecting lithium-ion stacks while managing cell balance autonomously. The device integrates safety features necessary for portable electronics and industrial applications where space and power efficiency are critical design parameters.

Battery Management Replacement Considerations

Check for other variants within the BQ77915 family that may offer different pinouts or packaging options. Verify if alternative TI battery protectors provide similar stackable features but with different quiescent current specifications or balancing methods.
