USB BC 1.2 compliant battery charging detector from Diodes

Diodes has introduced the dual-role PI3USB9201 USB BC 1.2 detector, which incorporates both host and client circuitry, enabling designers to optimise the BoM size and cost of adding USB Type-C interface circuitry in devices.

The PI3USB9201 enables developers to fully support the reversible and bidirectional flexibility of the USB Type-C interface with a single chip.

The device reports detection results to the system via a 1MHz I2C interface. Four-pin selectable slave addresses help avoid bus conflict.

When configured as a host, the PI3USB9201 broadcasts the device status as standard downstream port (SDP), charging downstream port (CDP), or dedicated charging port (DCP) via the USB D+/D- pins, in accordance with BC 1.2. As a client, the PI3USB9201 monitors the D+/D- pins to detect the attached host type.

Featuring differential pass-through USB switches, the PI3USB9201 supports USB switch pass-through in host mode to permit system wakeup via mouse or keyboard. Further attributes include a wide supply-voltage range of 2.7V to 5.5V, ensuring dependable operation in battery-powered equipment and energy-saving sub-1µA current in shutdown mode.

The PI3USB9201 is in production now in the 2mm x 2mm 12-pin QFN package.
