BQ24003PWPG4

Battery Chargers Overview

The BQ24003PWPG4 is a linear Li-Ion charge management IC from Texas Instruments, housed in a 20-pin HTSSOP package. It supports Lithium-ion and Lithium Polymer batteries with a fixed output voltage of 4.2 V and an output current capability of 1.2 A. The device operates within a supply voltage range of 4.5 V to 10 V and functions across a temperature range of 0°C to +70°C.

Battery Chargers Feature Summary

• Linear charging architecture for single-cell lithium batteries
• Integrated thermal regulation to manage power dissipation
• Supports standard constant-current/constant-voltage charging profiles

Battery Chargers Applications

• Portable electronic devices requiring single-cell Li-Ion power
• Battery-powered consumer electronics
• Industrial control modules with limited space

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the HTSSOP-20 package dimensions match your PCB footprint requirements. Ensure input voltage sources remain within the specified 4.5 V to 10 V operational range to prevent device malfunction or damage during procurement validation.

Battery Chargers Selection Notes

Select this component when a simple linear solution is preferred over switch-mode architectures for low-noise applications. It is suitable for systems where efficiency is secondary to cost and board space constraints. Verify that the thermal environment allows for adequate heat dissipation given the linear topology and maximum output current specifications.

Battery Chargers Part Context

This part belongs to the BQ24003 series of battery chargers. It shares functional similarities with other single-cell linear chargers but is distinct from switch-mode variants like the BQ24400 series. The G4 suffix typically denotes environmental compliance modifications rather than functional changes within the same product family.

Battery Chargers Replacement Considerations

Direct substitutes include other BQ24003 variants with different packaging or suffixes, such as BQ24003PWP. Cross-referencing with similar linear chargers requires verifying pin compatibility and electrical parameters.
