Overview

This 5-V USB, 2-cell battery boost charger reference design includes a charger system and a 2-cell battery holder with a gauge that can be connected by a cable or work independently. The key components of the charger system include the BQ25883 boost charger, TUSB320LAI Type-C CC logic, MSP430FR2433 microcontroller (MCU), OLED display, USB Type-C and Micro B connecters. The battery gauge is BQ28Z610, which combined with the internal ADC of BQ25883, display the charge and battery parameters. This design can be connected to your own system via a signal connector J5, making it a plug-in turnkey solution. The design is suitable for portable electronics applications, such as POS, Bluetooth® speakers and portable printers.

Features
  • Bidirectional charging and on-the-go (OTG) operation for a 5-V USB 2-cell battery system
  • Supports USB Type-C dual role port (DRP), USB 3.0 and BC1.2
  • System can be divided into two independent parts
  • OLED displays charging parameters and battery status in real time
  • Merge to external system easily
