Design files

Overview

TIDA-00280 is an evaluation module for fully-integrated single-cell NVDC 3A charger bq24296/bq24297 with 1.5A synchronous boost operation. This board could be used to evaluate the performance of USB detection, the flexibility to change the charging profile and OTG operation. The two charger ICs are widely used in personal portable electronics including smart phone, tablets and WiFi routers.

Features
  • Fast charging with up to 3A charging current to support high capacity battery pack
  • Input voltage regulation (VDPM) to support third party adapters
  • D+/D- USB detection compatible to USB BC1.2, non-standard adaptor detection
  • 1.5A OTG with adjustable output voltage
  • Pin-to-pin compatible to bq2419x

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
