Product details
Overview
BQ24260YFFR from Texas Instruments is a host-controlled, single-input, single-cell Li-ion battery charger IC with integrated power-path management and USB-OTG boost capability. It delivers up to 3 A charge current at 5% accuracy, supports 30-V input with overvoltage protection, and features Charge Time Optimizer (CTO) for accelerated CC/CV transition in smartphones and portable media players.
For engineers reviewing the BQ24260YFFR datasheet, BQ24260YFFR pinout, BQ24260YFFR application, or BQ24260YFFR equivalent, key selection considerations include its 2.4-mm × 2.4-mm DSBGA-36 package, I²C-programmable charge voltage (3.5–4.44 V), JEITA-compatible NTC monitoring via TS pin, and 93% peak efficiency in buck charging mode.
Technical Context
The BQ24260YFFR implements a synchronous buck converter topology with integrated 17-mΩ power-path MOSFET and external gate drive for BGATE-controlled discharge FET. Its power-path architecture enables simultaneous system powering and battery charging while allowing battery supplementation during high SYS load transients.
Charge control uses three-phase sequencing (precharge, constant-current, constant-voltage) with thermal regulation active above 125°C and programmable safety timer. USB-OTG boost mode configures the device to supply 5 V/1 A from battery to IN pin using internal switching elements and DRV-biased gate drive.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-cell Li-ion charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ24261YFFT | Same YFF package; default input current limit = 14 A (disabled), no D+/D– detection, no CD pin. | Targeted for systems where USB enumeration is handled externally; lacks hardware disable (CD) and USB ID detection. | Select BQ24261YFFT when host processor fully manages input detection and no hardware disable is needed. |
| BQ24262YFFR | Same YFF package; lower 6-V OVP threshold, no D+/D– detection, fixed 4.2-V charge voltage, no CD pin. | Designed for low-voltage USB-only inputs; lacks USB ID sensing and programmable charge voltage. | Choose BQ24262YFFR only for cost-sensitive USB-IF compliant designs with fixed 4.2-V battery chemistry. |
Compared with BQ24260YFFR, BQ24261YFFT removes D+/D– detection but retains CD disable and full I²C configurability, while BQ24262YFFR sacrifices flexibility for USB-specific simplicity and lower OVP-neither offers direct pin compatibility nor identical feature parity.

FAQ
What is the maximum input voltage rating for the BQ24260YFFR?
The BQ24260YFFR has an absolute maximum input voltage rating of 30 V on the IN pin, with recommended operating range of 4.2 V to 10 V. This 30-V rating provides robustness against transient surges from wall adapters or automotive USB sources, while the internal overvoltage protection triggers at 10.5 V nominal to safeguard downstream circuitry before reaching absolute limits.
Does the BQ24260YFFR support JEITA-compliant battery charging?
Yes, the BQ24260YFFR supports JEITA-compliant charging via its dedicated TS pin, which implements four programmable voltage thresholds corresponding to cold, cool, normal, warm, and hot temperature zones. When paired with a standard NTC thermistor and resistor divider, the BQ24260YFFR automatically suspends or resumes charging based on measured battery temperature-fully meeting JEITA JIS C 8712 requirements without external microcontroller intervention.
Can the BQ24260YFFR operate without an external inductor?
No, the BQ24260YFFR requires an external inductor connected between the SW pin and the input/output filter network. The device uses a synchronous buck topology with internal high- and low-side MOSFETs, and the inductor value must be between 1.5 µH and 2.2 µH (as specified in the datasheet) to ensure stable operation, proper current ramp control, and peak efficiency. Omitting the inductor will prevent functional charging or power-path operation.
What is the purpose of the CD pin on the BQ24260YFFR?
The CD (Chip Disable) pin on the BQ24260YFFR provides hardware-level enable/disable control: driving CD high places the device in high-impedance mode-disabling all internal regulators, switching, and battery FETs while drawing only 250 µA quiescent current. Driving CD low enables normal operation. This pin allows system-level power gating independent of I²C commands, making it essential for low-power standby states or fault isolation in battery-powered devices using the BQ24260YFFR.
Is the BQ24260YFFR pin-compatible with other devices in the bq2426x family?
No, the BQ24260YFFR is not pin-compatible with other bq2426x variants in the same YFF package. Although all share the 36-pin DSBGA footprint, pin functions differ significantly-for example, BQ24261YFFT omits the CD pin and reassigns D+/D– pins as NC, while BQ24262YFFR removes both CD and D+/D– and adds PSEL functionality. PCB layout must be tailored specifically for BQ24260YFFR; no mechanical or electrical drop-in replacement exists within the family.
