Battery Chargers datasheet and documents for BQ24702PWG4

BQ24702PWG4

Battery Chargers Overview

The BQ24702PWG4 is a multi-chemistry battery charger controller and system power selector designed for notebook applications. It features dynamic power management to maximize charging time by adjusting current based on available wall adapter power. The device utilizes a fixed-frequency PWM controller for precise charge control, supporting input voltages up to 28V. It operates within a temperature range of -40°C to 85°C and is housed in a 24-TSSOP package.

Battery Chargers Feature Summary

Integrates dynamic power management to optimize charging duration by dynamically adjusting battery current relative to total system current limits.
Includes an integrated power selector allowing manual selection between AC, battery, or wall adapter sources with automatic switchover capabilities.
Provides high-precision voltage regulation suitable for lithium-ion chemistry requirements through internal reference options.

Battery Chargers Applications

Notebook computer battery charging systems
Sub-notebook portable device power management
Multi-chemistry battery management architectures

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance status as per Texas Instruments documentation. Confirm the package type matches the required 24-TSSOP footprint for PCB layout compatibility. Ensure the component meets the specified operating temperature range for the intended deployment environment.

Battery Chargers Selection Notes

Select this component when designing systems requiring simultaneous power delivery and battery charging from a single AC adapter source. It is appropriate for applications needing precise voltage regulation for lithium-ion cells without external complex circuitry. Consider the 24-pin TSSOP form factor for space-constrained motherboard designs.

Battery Chargers Part Context

This part belongs to the BQ2470x series of battery chargers from Texas Instruments. It shares functional similarities with the BQ24703 but lacks specific advanced features found in higher-tier models. The series is engineered for portable computing devices requiring efficient power path management.
