Battery Chargers datasheet and documents for BQ24159YFFT

BQ24159YFFT

Battery Chargers Overview

The BQ24159YFFT is a fully integrated switch-mode single-cell lithium-ion battery charger manufactured by Texas Instruments. It operates within an input voltage range of 4 V to 9 V and provides a maximum output charging current of 1.5 A. The device features an adjustable output voltage and is housed in a compact 20-pin DSBGA package. Designed for surface-mount installation, it supports operation across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

Fully integrated switch-mode architecture designed for single-cell lithium-ion and lithium-polymer batteries
Comprehensive USB compliance ensuring safe charging from standard host ports
Integrated power path management for system power sharing

Battery Chargers Applications

Portable consumer electronics requiring USB-powered charging
Smartphones and mobile communication devices
Personal digital assistants (PDAs) and handheld gadgets

Battery Chargers Procurement Notes

Verify the specific suffix YFFT corresponds to the 20-DSBGA package configuration during procurement. Confirm that the required input voltage source falls within the 4 V to 9 V operational range. Ensure thermal management strategies align with the specified -40°C to +85°C operating temperature limits for the target application environment.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell Li-Ion/Polymer charging via USB is required. It is suitable for designs needing integrated power path management without external MOSFETs. Consider the 20-DSBGA footprint constraints and verify compatibility with available 4 V to 9 V input sources before finalizing the design.

Battery Chargers Part Context

This part belongs to the BQ24159 series of battery chargers from Texas Instruments. It is categorized under PMIC - Power Management ICs specifically for charge management. The device is distinct from higher-current variants like the BQ24165 or BQ24257 due to its 1.5 A limit and specific 20-pin packaging.
