1.2 General Description

The bq24153A/56A/57/58/59 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 bq24153A/56A/57/58/59 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 bq24153A/56A/58/59 data sheet (SLUSAB0) and the bq24157 datasheet (SLUSAX5).
