It delivers a programmable constant charge current up to 500 mA and terminates at a 4.2 V battery pack voltage. ## Charge current, timer, and fault protection Charge current is set by an external resistor — the constant-programmable method lets the BOM engineer choose the rate per cell capacity. A programmable timer backs up the termination; if the battery never reaches 4.2 V within the window, the part stops charging rather than cook the cell. Fault protection covers over-temperature, over-voltage, reverse current, and short circuit — four conditions that cover the common failure modes in a portable device: a stalled fan, a hot-plug surge, a dead battery sinking current, or a solder bridge on the output. ## Active production — no end-of-life watch needed It ships in Tape & Reel (TR) or Cut Tape (CT), which covers both high-volume reel feed and prototype or rework quantities. The base product number BQ24232 shares the same die and package family — if a future revision appears, the RGTR suffix will carry the change.","metaTitle":"BQ24232RGTR Texas Instruments Li-Ion Charger, USB, 500 mA","metaDescription":"BQ24232RGTR single-cell Li-Ion charger with USB interface, 500 mA max charge current, -40°C to 125°C junction range, 16-VQFN package.

The maximum supply voltage is 10.2 V, which covers both standard 5 V USB and the 9 V USB-C PD profile. The part negotiates the input current limit through the D+/D- lines per the USB battery-charging specification."},{"question":"Can the BQ24232RGTR charge a 4.2 V Li-Po battery?","answer":"Yes, the battery pack voltage is 4.2 V, which is the standard termination voltage for a single-cell Li-Po or Li-ion cell. The charge current is programmable up to 500 mA, so a 1000 mAh cell charges in roughly two hours at the full rate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24232RGTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24232RGTR when reusing this data.
