BQ24008PWP

Battery Chargers Overview

The BQ24008PWP is a linear single-cell lithium-ion battery charger manufactured by Texas Instruments. It integrates the power path management and an internal N-channel MOSFET switch, eliminating the need for external current sensing resistors and blocking diodes. The device operates within a supply voltage range of 4.5 V to 10 V and supports a maximum charge current of 1.2 A. It provides a regulated 4.2 V output for the battery cell. The component is housed in a 20-pin PowerTSSOP package with dimensions of 6.5 mm x 4.4 mm x 1.15 mm and functions across a temperature range of -40°C to +70°C.

Battery Chargers Feature Summary

• Integrates power path management with an internal N-channel MOSFET switch for system load prioritization

Battery Chargers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and environmental compliance status. Ensure the ordering code matches the required thermal performance and lead-free specifications. Cross-reference the manufacturer's latest documentation to validate active production status and any recent design changes before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell lithium-ion charging is required without external blocking diodes. It is suitable for applications where the input voltage source can support the necessary headroom for linear regulation. Consider the thermal dissipation capabilities of the PowerTSSOP package relative to the expected charge current and ambient operating conditions.

Battery Chargers Part Context

This part belongs to the BQ2400x family of battery chargers from Texas Instruments. These devices are designed for portable applications needing efficient power path management. The BQ24008 variant specifically offers integrated switching capabilities to manage system loads during charging, distinguishing it from simpler linear charger architectures that lack power path control features.

Battery Chargers Replacement Considerations

Consult official substitution guides for verified alternatives such as the BQ24003 or BQ24007 series. Confirm pin compatibility and electrical parameter alignment before replacing the component.
