Overview

The BQ25611DEVM evaluation module (EVM) uses the BQ25611D device, a 3-A, 1-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. The EVM also features USB BC1.2 and non-standard adapter detection.

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 20 mA ± 10 mA termination current
  • USB BC1.2 and non-standard adapter detection
