1.2 General Description

The BQ24150/150A/151/151A/152 evaluation module is a complete charger module for evaluating

compact, flexible, high-efficiency, USB-friendly switch-mode charge management solution for single-cell

Li-ion and Li-polymer batteries used in a wide range of portable applications.

The BQ24150/150A/151/151A/152 integrates a synchronous PWM controller, power MOSFETs, input

current sensing, high-accuracy current and voltage regulation, and charge termination, into a small WCSP

package.

The charge parameters can be programmed through an I

C interface.

For details, see the appropriate data sheets (SLUS824, SLUS847, SLUSA27, and SLUS931).
