BQ25601RTWR

Battery Chargers Overview

The BQ25601RTWR is an I2C-controlled single-cell buck battery charger from Texas Instruments, designed for high input voltage and NVDC power path management. It supports a maximum charging current of 3A with a minimum programmable limit of 60mA. The device operates within a supply voltage range of 3.9V to 13.5V and delivers a regulated output voltage of 6V. It features a 24-WQFN package (4x4mm) suitable for surface mount installation. The component supports lithium-ion and lithium-polymer batteries, operating across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates NVDC power path management to balance system load and battery charging simultaneously.
• Supports I2C interface for precise control and status monitoring via host communication.
• Includes hardware watchdog timer and thermal regulation for enhanced safety.
• Provides configurable fault protection against over-temperature and over-voltage conditions.

Battery Chargers Applications

• Smartphones and mobile phones
• Wearable electronic devices such as smartwatches
• Portable consumer electronics requiring single-cell Li-Ion/Polymer charging

Battery Chargers Procurement Notes

Verify the specific suffix RTWR corresponds to the Reel packaging configuration when sourcing. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid cut-tape discrepancies. Cross-reference the datasheet revision date to confirm the latest electrical specifications and application circuit recommendations are utilized during design validation.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell battery charging with integrated power path management. It is suitable for systems where the input voltage may exceed the battery voltage, allowing direct system powering during charge. Consider the I2C interface requirement for dynamic current adjustment and fault monitoring. Evaluate the 24-WQFN footprint constraints against your PCB layout capabilities.

Battery Chargers Part Context

This part belongs to the BQ25601 series of battery chargers from Texas Instruments. It is functionally equivalent to variants like BQ25601RTWT and BQ25601RTWRG4, differing primarily in packaging type or environmental compliance markings.
