It supports a programmable constant charge current up to 2 A and accepts a maximum supply voltage of 6.5 V. Communication with a host microcontroller runs over an I²C interface, and the device is compatible with USB charging sources. A programmable timer is the only on-chip feature the user can configure. ## Protection and temperature range Built-in fault protection covers over-temperature and over-voltage conditions, critical for safe single-cell Li-ion charging in portable equipment. ## Package and mounting Housed in a 30-ball DSBGA package, this is a surface-mount device. The supplier device package is 30-DSBGA.","metaTitle":"BQ24257YFFT single-cell charger IC, NRND, 2A max, I²C/USB","metaDescription":"Texas Instruments BQ24257YFFT single-cell Li-ion charger IC.
