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
