1-cell Li-Ion charger with USB interface and 1A charge current
The Texas Instruments BQ24093DGQR is a linear battery charger IC for single-cell Lithium Ion/Polymer packs, delivering a programmable constant charge current up to 1 A with a regulated 4.2 V battery termination voltage. The USB interface allows direct connection to a standard USB port or a dedicated charging adapter, with the maximum supply voltage rated at 6.45 V. Fault protection includes over-temperature, over-voltage, and short-circuit monitoring, covering the primary failure modes in portable equipment charging.
Package and thermal footprint for PCB integration
The BQ24093DGQR is supplied in a 10-lead HVSSOP package, also described as a 10-PowerTFSOP or 10-MSOP with a 3.00 mm body width. Surface-mount assembly with Tape & Reel or Cut Tape packaging suits automated pick-and-place lines.
Active lifecycle and compliance documentation
The base product number is BQ24093; the DGQR suffix denotes the 10-HVSSOP package and tape-and-reel packaging variant.
