The supply max is 6.4V, which covers USB VBUS (5V nominal) plus a healthy margin for cable drop and hot-plug transients. The charger uses a constant-current / constant-voltage profile with programmable current and timer via external resistors. Fault protection covers over-temperature, over-voltage, reverse current, and short circuit — no external supervisor needed for those events.","metaTitle":"BQ24073RGTT — TI Li-Ion 1-Cell USB Charger, 1.5A, 16-QFN","metaDescription":"BQ24073RGTT: Active-production single-cell Li-Ion charger from TI.

Actual time depends on the cell's internal resistance and the thermal regulation threshold — the exposed pad must be well-sinked to sustain 1.5A without throttling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24073RGTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24073RGTT when reusing this data.
