Introduction

AI Translation

The bq24153A/6A/8/9 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.
