Single-cell Li-Ion linear charger with programmable current and timer
The Texas Instruments BQ24010DRCR is a single-cell linear charger IC from the bqTINY™ series, designed for Li-Ion and Li-Polymer battery packs. It delivers a programmable charge current up to 1A and terminates at a fixed 4.2V battery regulation voltage. The input supply range extends to 16.5V max, giving headroom for common 5V USB or wall-adapter rails without an external pre-regulator in many designs.
Package, footprint, and temperature grade for board integration
Housed in a 10-VFDFN exposed-pad package (10-VSON, 3x3 mm), the BQ24010DRCR mounts on a standard surface-mount footprint. Rated for operation from -40°C to +125°C junction temperature, this IC suits portable equipment that sees both cold storage and warm charging environments — handheld instruments, wearables, and medical devices with a single-cell pack.
