Overview

The BQ25619 evaluation module (EVM) is used to evaluate the BQ25619 device. This is a 3-A single-cell battery charger optimized for power bank applications in low-power portable designs. The OTG reverse synchronous boost operation and forward buck mode operation allows for control over power delivery to peripherally powered devices.

Features
  • 92% charge efficiency at 2-A from 5-V input and 92% boost efficiency at 1-A output
  • Output short circuit protection and soft-start up to 500-µF capacitive load in OTG mode
  • 10-µA low battery leakage current with system voltage standby 3-µA low battery leakage current in ship mode
  • BATFET control to support ship mode, wake up and full system reset
  • High accuracy at 20 mA, ±10-mA termination current
