Diodes Incorporated<\/a><\/strong> announces the dual-role 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 such as laptops, tablets, smartphones, drones, and small home appliances.<\/p>\n\n\n\n

Unlike current market solutions that require devices dedicated to either host or client mode, the PI3USB9201 enables developers to fully support the reversible and bidirectional flexibility of the USB Type-C interface with a single chip. <\/p>\n\n\n\n

The PI3USB9201 reports detection results to the system via a 1MHz I2C interface. Four-pin selectable slave addresses help avoid bus conflict. <\/p>\n\n\n\n

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. <\/p>\n\n\n\n

As a client, the PI3USB9201 monitors the D+\/D- pins to detect the attached host type.<\/p>\n\n\n\n

Featuring differential pass-through USB switches, the PI3USB9201 supports USB switch pass-through in host mode to permit system wakeup via mouse or keyboard. <\/p>\n\n\n\n

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-1\u00b5A current in shutdown mode.<\/p>\n\n\n\n

The PI3USB9201 is in production now in the 2mm x 2mm 12-pin QFN package.<\/p>\n","protected":false},"excerpt":{"rendered":"
