It delivers a programmable constant charge current up to 1.5A and accepts a supply voltage up to 16V, making it suitable for both USB and adapter inputs. ## Charge current, timer, and fault protection The charge current is constant and programmable via an external resistor; a programmable timer terminates the charge cycle after a set period. Built-in fault protection covers over-temperature, reverse current, and short-circuit conditions — no external monitoring components needed for these safeguards. Store the reels dry — the VQFN package is MSL-sensitive and requires dry-bake before reflow if the moisture barrier bag is compromised.","metaTitle":"BQ24031RHLR Li-Ion Battery Charger IC, 1.5A, USB Interface","metaDescription":"Texas Instruments BQ24031RHLR single-cell Li-Ion/Polymer charger IC. 1.5A max charge current, USB interface, 16V max supply.

Charging a standard 4.2V Li-ion cell with this part would overcharge the cell — use a charger IC with a 4.2V regulation point instead."},{"question":"Is BQ24031RHLR compatible with USB charging?","answer":"Yes, the BQ24031RHLR accepts a USB input through its USB interface. The maximum supply rating of 16V also allows use with higher-voltage wall adapters, but the charge current must be programmed to stay within the USB port's current capability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24031RHLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24031RHLR when reusing this data.
