Overview

The BQ25618EVM is an evaulation module (EVM) used to test the BQ25618 device, a 1.5-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

94% charge efficiency at 1 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
