TIDA-00046

Design files

Overview

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.

Features
  • # Series Cells: 1S
  • Max Input Volts: 6V
  • Max Charge Current: 1.25A
  • Topology: Switch mode
