Description

This reference design is featured in solar lithium battery applications. This design, which contains an integrated switch-mode battery charge controller, provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel, the input regulation loop maintains the panel at maximum power output. This solution is also called the HPA639 A. The manual includes the  bill of materials, board layout, and schematic. The user's guide describes the features and operation of the solution.

Features
  • # Series Cells: 1 to 6S
  • Max Input Volts: 28V
  • Max Charge Current: 8A
  • Topology: Switch mode
  • Communication: Standalone
  • Features:  Programmable Maximum Power Point Tracking (MPPT) for Solar Panel;
  • Adjustable charge voltage
