BQ25616RTWR

Battery Chargers Overview

The BQ25616RTWR is a standalone, single-cell buck battery charger from Texas Instruments designed for lithium-ion and lithium-polymer batteries. It integrates a 3A switch-mode charging controller with a highly integrated power path management system. The device features an input reverse blocking FET (RBFET), high-side switch FET (HSFET), low-side switch FET (LSFET), and battery FET (BATFET). It operates within a supply voltage range of 4V to 13.5V and delivers up to 3A output current. The maximum output voltage is 4.35V. The component is housed in a WQFN-24 package and supports surface-mount installation.

Battery Chargers Feature Summary

• Integrates input reverse blocking FET, high-side switch FET, low-side switch FET, and battery FET for compact design
• Optimizes system efficiency through low-impedance power path management
• Supports programmable charging current for flexible system requirements

Battery Chargers Applications

• Smartphones and mobile phones
• Tablets and portable media players
• Bluetooth headsets and wearable devices
• Portable medical equipment

Battery Chargers Procurement Notes

Verify the specific suffix 'RTWR' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Cross-reference the pinout and thermal pad configuration with the WQFN-24 footprint data before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when a highly integrated solution for single-cell Li-ion or Li-Po batteries is required. It is suitable for applications needing efficient power path management to extend battery runtime. Consider the 3A current limit and 13.5V input voltage ceiling to ensure alignment with system power source capabilities and battery chemistry constraints.

Battery Chargers Part Context

This part belongs to the BQ25616 series of battery chargers. It is functionally related to variants such as BQ25616RTWT and BQ25616JRTWR, which share similar core architectures but may differ in packaging or specific electrical tolerances. The series is designed for consumer electronics requiring efficient, space-constrained charging solutions.

Battery Chargers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BQ25616JRTWT and BQ25616RTWR. Verify that any replacement matches the original part's package type and electrical specifications before implementation.
