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
