At that current, the 20-bump DSBGA package relies on the PCB copper pour for heat spreading — the thermal pad on the back of the package must be soldered to a solid ground plane to keep junction temperature below the 125°C limit. Built-in over-voltage and over-temperature protection shut down the charger if the battery or die exceeds safe limits. The safety timer is also programmable, so a stuck battery or failed thermistor won't leave the charger pumping current indefinitely. ## Active production — no LTB pressure Supplied in Tape & Reel (TR) or Cut Tape (CT) for the 20-DSBGA package. The DSBGA bumps are on a 0.5 mm pitch — a stencil with 0.3 mm aperture and a reflow profile matching the JEDEC MSL-1 rating are recommended for assembly yield.","metaTitle":"BQ24150AYFFR Texas Instruments Li-Ion Charger IC – 1.25A","metaDescription":"Texas Instruments BQ24150AYFFR single-cell Li-Ion/Polymer charger IC. 1.25A max charge current, I²C programmable, -40°C to 85°C, 20-DSBGA.
