Introduction
The BQ24932EVM is an evaluation module for TI's BC1.2-compatible charger detection IC with an
integrated USB 2.0 high-speed isolation switch. In addition to detecting BC1.2-compliant chargers, the
BQ24932 is also able to detect Apple and TomTom chargers, allowing the system containing the
BQ24392 to charge from more types of chargers, enhancing the end-user experience.
The evaluation module is designed to easily demonstrate the capabilities of the BQ24392 without the need
for external supplies or metering equipment through the use of status indicator LEDs. See
for the
EVM block diagram.
