Single-cell Li-Ion charger with I²C programmability
The Texas Instruments BQ24272YFFT is a single-cell lithium-ion battery charger IC in a 49-DSBGA package (2.8x2.8 mm). It delivers a programmable charge current up to 2 A, controlled via an I²C interface, making it suitable for space-constrained portable designs.
Charge current and protection
The maximum charge current of 2 A is constant-current programmable through the I²C bus, so the charge profile can be tuned to the battery capacity without external resistors.
Package and temperature grade
Housed in a 49-bump DSBGA (2.8x2.8 mm), the BQ24272YFFT is a wafer-level chip-scale package — the footprint matches the die size, so the PCB land pattern must follow TI's recommended layout for solder-joint reliability.
