BQ24153 datasheet


The bq24153/6/8 is a compact, flexible,high-efficiency, USB-friendly switch-mode charge
management device for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. The charge parameters can be programmed through an I2C interface. The IC integrates a synchronous PWM controller, power MOSFETs, input current sensing, high-accuracy current and voltage regulation, and charge termination, into a small WCSP package.
