The I²C bus lets you set the charge current and safety timer without external resistors — a space-saving advantage on a 20-DSBGA package. ## Programmable current and timer via I²C Charge current is constant and programmable through the I²C interface. The timer is also programmable, giving the host processor control over charge termination and safety timeout. ## Fault protection and battery voltage ceiling Built-in fault protection covers over-temperature and over-voltage conditions. The maximum battery pack voltage is 4.44 V, and the supply voltage ceiling is 6 V. The operating temperature range of -30°C to 85°C supports industrial and outdoor applications. ## Active production — sourcing and package details The supplier device package is 20-DSBGA, a 0.4 mm pitch wafer-level chip-scale package. Tape & Reel and Cut Tape options are available.","metaTitle":"BQ24158YFFR: TI Li-Ion Charger IC, 1.25A, I²C, 20-DSBGA","metaDescription":"Texas Instruments BQ24158YFFR single-cell Li-Ion battery charger. 1.25 A max charge current, I²C programmable, 20-DSBGA package.
