BQ25070DQCT

Battery Chargers Overview

The BQ25070DQCT is a single-cell linear battery charger IC designed for Lithium Iron Phosphate (LiFePO4) batteries. It provides a regulated 3.5 V output with a maximum charge current of 1 A. The device operates from a power supply voltage range of 3.75 V to 30 V and draws a typical operating supply current of 3 mA. Packaged in a WSON-10 surface-mount format, it supports an operating temperature range from -40°C to +85°C.

Battery Chargers Feature Summary

• Linear charging architecture optimized for LiFePO4 chemistry
• Integrated thermal regulation and overvoltage protection
• USB-compatible input interface

Battery Chargers Applications

• Single-cell LiFePO4 battery charging systems
• Portable electronic devices requiring safe iron phosphate cell management
• Power management modules for industrial or consumer applications

Battery Chargers Procurement Notes

Verify the specific suffix DQCT corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the component meets RoHS compliance standards applicable to your region. Ensure the supplier documentation explicitly references the Texas Instruments datasheet for the BQ25070 series to validate authenticity and technical specifications before integration.

Battery Chargers Selection Notes

Select this component when designing for LiFePO4 cells requiring a fixed 3.5 V termination voltage. The wide input voltage range accommodates various USB and wall adapter sources. Consider the WSON-10 package for space-constrained layouts. Verify that the 1 A current limit aligns with the target battery's acceptance characteristics and thermal constraints within the final enclosure.

Battery Chargers Part Context

This part belongs to the BQ25070 family of single-cell linear chargers. It is distinct from the BQ25071, which may offer different electrical characteristics or automotive qualifications. The DQCT designation indicates a specific reel-based packaging variant manufactured by Texas Instruments for high-volume surface mount production lines.
