BQ296227DSGR

Battery Management Overview

The BQ296227DSGR is a lithium-ion battery protection IC designed for single-cell applications. It integrates high-side N-channel MOSFET switches for both charge and discharge paths, eliminating the need for external pass elements. The device monitors cell voltage and current to provide over-voltage, under-voltage, over-current, and short-circuit protection. It features programmable thresholds via external resistors and includes a built-in temperature sensor for thermal management. The component operates within a supply voltage range of 2.0V to 5.5V and supports continuous currents up to 4A depending on external conditions.

Battery Management Feature Summary

• Integrated dual high-side N-channel MOSFETs for compact charge and discharge control
• Programmable protection thresholds for voltage and current limits
• Built-in thermal monitoring with automatic shutdown capabilities
• Low quiescent current operation for extended battery life

Battery Management Applications

• Portable consumer electronics such as smartphones and tablets
• Power tools requiring single-cell lithium-ion battery packs
• Medical devices with strict safety requirements for battery management
• IoT sensors and wearable technology utilizing small form factor batteries

Battery Management Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the intended tape-and-reel packaging and temperature grade. Confirm that the ordering part number matches the exact pinout and functional specifications required by your design. Cross-reference with the manufacturer's latest datasheet to ensure compliance with updated regulatory standards or revision changes before finalizing procurement.

Battery Management Selection Notes

Select this component when a compact solution for single-cell lithium-ion protection is required without external MOSFETs. Ensure the application current does not exceed the internal switch ratings under worst-case thermal conditions. Verify that the programmable resistor values align with the desired protection thresholds defined in the electrical characteristics table of the official documentation.

Battery Management Part Context

This device belongs to Texas Instruments' family of battery protection ICs aimed at simplifying design for portable electronics. It replaces discrete protection circuits by integrating sensing and switching functions into a single small outline package. The series emphasizes reliability and space efficiency for modern mobile devices where board real estate is limited.

Battery Management Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the same product family that offer similar integrated MOSFET configurations. Verify that any substitute maintains identical protection threshold ranges and package dimensions to avoid redesigning the PCB layout or adjusting external component values.
