Description

PI3USB9281C provides external detection for any USB-device. The part can detect various chargers available in the market, MHL accessories, OTG accessories, and car-chargers per the CEA936 spec. It also integrates a power switch with over-voltage and over-current protections. The VBUSIN input pin can tolerate voltages up to 28V, which is important for USB3.0-PowerDelivery enabled ports. The new USB-3.0-PowerDelivery specification supports voltages up to 20V. The PI3USB9281C can operate over a temperature range of -40°C to +85°C. Typical applications involve portable & consumer applications, such as tablet, smart phones, digital cameras, and notebooks with integrated Li-ion batteries that charge via USB connectors.
