BQ25176JDSGR

Battery Chargers Overview

The BQ25176JDSGR is a single-cell linear battery charger from Texas Instruments, designed for lithium-ion, lithium polymer, and LiFePO4 chemistries. It delivers an 800 mA charge current with a 3 V to 6.6 V input voltage range. The device features dynamic power management (DPM) to optimize system power usage. It supports programmable charge voltages of 4.15 V, 4.2 V, 4.35 V, and 4.4 V for Li-Ion/Polymer, and 3.5 V, 3.6 V, and 3.7 V for LiFePO4. The IC includes thermal regulation, input overvoltage protection up to 30 V, and operates in a WSON-8 package.

Battery Chargers Procurement Notes

Verify the specific suffix 'J' against the official datasheet to confirm exact configuration parameters. Ensure compatibility with the target battery chemistry and required charge voltage settings. Confirm that the WSON-8 package footprint matches the design layout. Validate thermal performance requirements under maximum load conditions.

Battery Chargers Selection Notes

Select this component for space-constrained portable applications requiring integrated linear charging. Consider the 800 mA output limit and 30 V input tolerance when designing the power path. Evaluate the need for specific charge termination voltages supported by the J variant compared to other family members.
