BQ24002PWPG4

Battery Chargers Overview

The BQ24002PWPG4 is a linear single-cell lithium-ion battery charger manufactured by Texas Instruments. It integrates a power path management controller, an N-channel MOSFET switch, and a linear charge regulator within a 20-pin HTSSOP package. The device supports input voltages from 4.5 V to 10 V and provides programmable charge current up to 1.2 A. It features two status LEDs for indicating charge activity and system status. The IC includes thermal regulation to limit die temperature during high-power charging operations.

Battery Chargers Feature Summary

• Integrates power path management with automatic switchover between input source and battery
• Includes built-in N-channel MOSFET for precise linear charge regulation
• Provides dual LED outputs for configurable status indication of charge state

Battery Chargers Applications

• Portable consumer electronics requiring single-cell Li-Ion power
• Handheld devices utilizing USB or wall adapter power sources
• Battery-powered systems needing integrated power path management

Battery Chargers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the package type matches the 20-HTSSOP outline and ensure the suffix indicates lead-free compliance. Cross-reference the date code and lot number with the supplier's certificate of analysis to guarantee material integrity and traceability.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell lithium-ion charging is required without external switching FETs. It is suitable for applications where power path management simplifies system design by allowing simultaneous operation and charging. Consider the thermal performance requirements as the device relies on linear regulation and internal thermal limiting.

Battery Chargers Part Context

This part belongs to the bqTINY family of battery chargers designed for space-constrained portable applications. It represents a generation of integrated solutions that combine control logic and power stages into a small footprint. The G4 suffix typically denotes a specific manufacturing revision or compliance update within the product line.

Battery Chargers Replacement Considerations

Direct pin-to-pin replacements may include other variants within the bq2400x series such as the BQ24003 or BQ24005, provided they share the same package and electrical characteristics. Verify compatibility regarding charge current limits and LED configuration before substitution.
