1.1 EVM Features

This EVM supports the following features:

  • Evaluation module for the BQ25620 or BQ25622 devices.
  • Narrow VDC (NVDC) power path management for powering the systems and charging the battery.
  • Supports I2C communication for systems configuration and status reporting.
  • Test points for key signals available for testing purposes.
  • Jumpers for easy configuration.
  • One push-button for wake-up and reset input with adjustable timers.
  • Charge status (STAT) and Power Good (PG) LEDS for charging monitoring.
  • Connections for EV2400 or USB2ANY interface board controllers.

This EVM does not include the EV2400 or USB2ANY interface boards. To evaluate the EVM, an EV2400 or USB2ANY must be ordered separately.
