Charge current is set with a single external resistor — no I²C, no firmware. The 250 mA max means this part is sized for cells in the 100–300 mAh range, common in TWS earbuds or coin-cell Li-ion replacements. ## Fault protections and junction temperature envelope Three hard-wired protections are on-chip: over-temperature, over-voltage, and short-circuit. Over-temperature shuts down the charger before the 125°C junction limit is exceeded — the die temperature, not ambient, triggers the trip. Over-voltage protects the cell from a runaway supply; short-circuit protects the input from a battery-side fault. The operating junction range of 0°C to 125°C covers industrial-grade portable enclosures, but note the 0°C floor: Li-ion charging below freezing is blocked by the protection logic. If your application charges in a cold environment (e.g., outdoor medical patch), the charger will hold off until the die warms above threshold. ROHS3 compliant. Confirm the 6-bump DSBGA footprint matches your board layout before committing — the 0.4 mm pitch bumps require a solder mask defined pad and a stencil aperture sized for the bump diameter.","metaTitle":"BQ25101YFPR Li-Ion Charger IC – 250 mA, 6-DSBGA","metaDescription":"Texas Instruments BQ25101YFPR single-cell Li-Ion/Polymer linear charger, 250 mA max, 6-DSBGA package.

The charger operates in constant-current mode until the battery reaches 4.2 V, then tapers. For cells above 300 mAh, consider a higher-current part in the BQ2510x family."},{"question":"Does the BQ25101YFPR include over-temperature protection?","answer":"Yes. Over-temperature, over-voltage, and short-circuit protection are all integrated. The thermal shutdown is triggered by the junction temperature, not ambient, so the die temperature ceiling of 125°C is the hard limit."},{"question":"Is the BQ25101YFPR compatible with 4.2 V lithium cells?","answer":"Yes. The battery pack voltage is 4.2 V, matching standard Li-ion and Li-Polymer termination voltage.
