Description

This reference design is a complete charger module for evaluating compact: flexible: high-efficiency: USB-friendly switch-mode charge management solutions for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. It 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 I²C interface.
