The 10-VSON (3x3) package with exposed pad provides a compact footprint for space-constrained ECU or sensor module designs while the pad aids thermal dissipation at the 1A charge rate. ## Input voltage range and charge current programming Maximum supply voltage is 6.5V, making the part suitable for 5V USB rails or regulated automotive supplies — not for direct 12V battery connection without a pre-regulator. Charge current is set by an external resistor (constant-current, programmable), and the safety timer is also resistor-programmable, allowing the designer to match the charge profile to the cell capacity and thermal budget of the enclosure.","metaTitle":"BQ24081QDRCRQ1 Automotive Li-Ion Charger, 1A, AEC-Q100","metaDescription":"Texas Instruments BQ24081QDRCRQ1 single-cell Li-Ion/Polymer charger, 1A max, -40°C to 125°C, AEC-Q100.
