BQ24157SYFFT by Texas Instruments

BATTERY CHARGER LI-ION/LI-POL DSBGA-20
Part Information
BQ24157SYFFT image
RoHS Compliant
Description
The bq24157S 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 DSBGA package. The IC charges the battery in three phases: conditioning, constant current, and constant voltage. The input current is automatically limited to the value set by the host.
