BQ25616RTWT

Battery Chargers Overview

The BQ25616RTWT 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 charge management system with a highly integrated power path. Key electrical parameters include a maximum output current of 3A, an output voltage of 4.35V, and an operating supply voltage range of 4V to 13.5V. The device operates within a temperature range of -40°C to +85°C and is housed in a WQFN-24 package.

Battery Chargers Feature Summary

• Integrates input reverse blocking FET, high-side switch FET, low-side switch FET, and battery FET for a compact solution.
• Optimizes efficiency through a low-impedance power path that reduces charging time and extends discharge runtime.

Battery Chargers Applications

• Single-cell lithium-ion battery systems
• Single-cell lithium-polymer battery systems
• Power path management for portable devices

Battery Chargers Procurement Notes

Verify the specific suffix (RTWT) against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration. Ensure the design supports the required 4V to 13.5V input range and 3A current capability. Confirm thermal management requirements for the WQFN-24 package under maximum load conditions.

Battery Chargers Selection Notes

Select this component for applications requiring a highly integrated, single-cell buck charger with up to 3A output. It is suitable where minimizing external component count is critical due to the internal integration of power switches. Verify compatibility with the target battery chemistry and input voltage source constraints.
