It delivers a constant charge current programmable up to 1.2 A maximum, with a regulated battery voltage of 4.2 V. Built-in over-temperature fault protection guards the die against thermal runaway during high-current charging or elevated ambient conditions. The device operates over a -40°C to 70°C ambient temperature range, suiting it for portable consumer, medical, and industrial handheld equipment where the charger shares the board with the application processor. ## Charge current and thermal budget At the 1.2 A maximum charge current, the linear regulator dissipates power as (VIN - VBAT) × ICHG. The programmable timer and current set resistor allow the designer to trade charge time against thermal budget. A lower current setting reduces dissipation and lets the part run in a smaller enclosure. Supplied in a 20-VQFN Exposed Pad package (5x5 mm body), the BQ24002RGWR is surface-mount only.","metaTitle":"TI BQ24002RGWR Li-Ion Battery Charger IC, 1.2 A Max Charge","metaDescription":"Texas Instruments BQ24002RGWR single-cell Li-Ion charger IC.

The BQ24002RGWR charges to a regulated 4.2 V battery voltage, which is the standard full-charge voltage for a 3.7 V nominal Li-Po cell. The constant-current charging profile and programmable timer suit both Li-Ion and Li-Po chemistries."},{"question":"Does BQ24002RGWR have built-in thermal regulation?","answer":"Yes, the part includes over-temperature fault protection that shuts down charging if the die temperature exceeds the safe operating limit. This is a thermal shutdown, not a foldback current limit — the charger stops until the die cools."},{"question":"What is the maximum charge current of BQ24002RGWR?","answer":"The maximum charge current is 1.2 A, set by an external resistor. The charger operates in constant-current mode until the battery reaches 4.2 V, then terminates."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24002RGWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24002RGWR when reusing this data.
