The constant-current / constant-voltage profile is standard for Li-ion charging, and the 250 mA limit makes this part a fit for small-capacity cells in wearables, hearables, and portable medical devices where the charge current must stay within the battery's safe C-rate. ## Charge current programmable, protection built in The charge current is constant and programmable via an external resistor — no I2C bus needed, which keeps the BOM simple for low-pin-count designs. Fault protection covers over-temperature, over-voltage, and short-circuit, so the charger can handle a misbehaving cell or a fault on the input rail without external clamp diodes. The supply voltage max is 6.45V, which means a standard 5V USB rail or a 5V wall adapter will work, but a 6V rail is the practical ceiling before the internal LDO drops out. ## Active production, 6-DSBGA package This is a 0.4 mm pitch wafer-level chip-scale package; the PCB land pattern must follow the TI recommended footprint for the DSBGA, and the assembly house needs experience with fine-pitch BGA reflow.","metaTitle":"BQ25100YFPR - Texas Instruments 1-Cell Li-Ion Charger","metaDescription":"Texas Instruments BQ25100YFPR single-cell Li-ion linear charger, 250 mA max charge current, 4.2V battery pack voltage.
