That input range covers USB 5V, 12V wall adapters, and unregulated DC bricks without needing a separate pre-regulator — one less part on the BOM. It belongs to the bqTINY™ series, which means the die is optimised for small portable gear where board area and thermal budget are tight. ## Programmable current and timer — no I²C needed Charge current and safety timer are set with external resistors, so no digital interface is required. That simplifies the firmware — the charger runs standalone once the PROG resistor is chosen. The constant-current phase is programmable, and the part terminates charge when the current drops below the threshold or the timer expires. Fault protection covers short-circuit on the output, which is the failure mode you see when a battery tab touches the shield or a connector pin folds over. The part shuts down the pass FET and latches off until the fault is cleared and the input is recycled.","metaTitle":"BQ24018DRCR Li-Ion Charger IC – 1A, 16.5V, bqTINY™","metaDescription":"Texas Instruments BQ24018DRCR single-cell Li-Ion/Polymer charger, 1A max, 16.5V input, -40°C to 125°C, 10-VSON.

The battery regulation voltage is 4.36V, which matches the 4.35V/cell chemistry used in many high-energy-density smartphone and wearable cells. Do not use it with multi-cell stacks or with LiFePO4 chemistry — the termination voltage is wrong."},{"question":"What is the maximum charge current of the BQ24018DRCR?","answer":"1A maximum, set by an external resistor from the PROG pin to ground. The actual current is 1000 / R_PROG (in kΩ) — for example, a 1 kΩ resistor programs 1A, a 2 kΩ resistor programs 500 mA. The linear pass element dissipates (V_IN - V_BAT) × I_CHG as heat, so at 1A with a 5V input and a 3.7V battery, the package must shed about 1.3W. The exposed pad is mandatory for that thermal load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24018DRCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24018DRCR when reusing this data.
