That 1A ceiling is the max you can program; if your pack is smaller than 1000 mAh, you will want to set the current lower via the ISET pin to stay within the cell's C-rate. The USB interface means it expects a 5V bus — the 6.45V absolute supply max gives headroom for a standard USB port, but a 5V rail is the practical input. ## Fault protection — over-voltage, over-temperature, short-circuit Three built-in fault protections are on the die: over-voltage (stops charging if the battery voltage drifts above the regulation point), over-temperature (thermal foldback or shutdown if the die gets too hot), and short-circuit (limits output current if the battery terminals are shorted). For a field-swappable battery device, these protections mean you do not need an external supervisor IC — the charger handles the safety checks itself. ## Package and mounting — 10-HVSSOP, 3.00mm width Housed in a 10-HVSSOP (3.00mm width, 0.118\" body), this is a small outline package with an exposed thermal pad underneath. Surface-mount only; no socket option for field swapping. ## Lifecycle — active, no obsolescence concern TI lists the BQ24092DGQT as Active. For a production BOM, this means you can design it in without planning for an immediate replacement — but keep an eye on TI's PCN page for any future EOL announcements.","metaTitle":"BQ24092DGQT Battery Charger IC, USB, 4.2V, 1A, Active","metaDescription":"Texas Instruments BQ24092DGQT single-cell Li-Ion/Polymer charger IC.
