Disadvantages: - Limited to USB charging applications - Requires external components for complete charging system implementation

Working Principles

The TPS2513AQDBVTQ1 operates by monitoring the voltage levels on the DM and DP lines of the USB port. It detects the presence of a dedicated charging port (DCP) based on specific voltage thresholds. Once a DCP is detected, the IC enables the charging functionality and communicates this information to the connected device.

During charging, the TPS2513AQDBVTQ1 regulates the output voltage to ensure compatibility with the connected device's requirements. It also monitors the current flow to protect against overcurrent conditions. In case of an overvoltage or short circuit event, the IC quickly shuts down the charging port to prevent damage to the charging system or the connected device.
