It handles a single cell with a maximum battery pack voltage of 4.44 V and delivers a programmable constant charge current up to 2 A. ## Obsolete — sourcing through independent distribution TI has marked the BQ24188YFFT as Obsolete. That means no further production runs; the only source is the surplus and broker channel. If you need a pin-compatible second source, you will have to evaluate alternatives from the BQ24188 family or a different charger IC — the datasheet should be your guide for that comparison. ## 36-DSBGA package — field-swap realities There is no visible pin-1 marker beyond the laser-marked dot on the top; orientation is critical and not obvious under a magnifier. Swapping this on site without a hot-air station and a microscope is not realistic — it is a lab-bench rework job. The supply voltage max is 13.2 V, so it can run from a standard 12 V rail or a 5 V USB bus with headroom. The I²C interface needs pull-up resistors sized for the bus capacitance — the charger itself does not include them.","metaTitle":"TI BQ24188YFFT Li-Ion Charger, I²C, 2A, 36-DSBGA – Obsolete","metaDescription":"Texas Instruments BQ24188YFFT single-cell Li-Ion charger with I²C interface, max 2A charge current, 36-DSBGA package.
