USB Port Protection with Charger Detection Features Description USB-device Charger detector PI3 USB9281 provides external Detection for any USB- Can tolerate with VBUS = 20V device. The part can detect various chargers available in USB Charging-type Detection the market, MHL accessories, OTG accessories, and car- Battery Charging ( ) DCP chargers per the CEA936 spec. It also integrates a power Battery Charging ( ) CDP switch with over-voltage and over-current protections. Battery Charging ( ) SDP The VBUSIN input pin can tolerate voltages up to 28V, Apple 1A, 2A, & dedicated chargers which is important for enabled Samsung-Fast chargers ports .

2 The new specification YD/T-1951 dedicated chargers supports voltages up to 20V. CEA-936 Carkit#1 and #2 chargers The PI3 USB9281 can operate over a temperature range Integrated Power FET of -40 to +85 C. VBUS Tolerance up to 28V Typical applications involve portable & consumer Over-Current Protection (OCP) applications, such as tablet, smart phones, digital VBUS Over-Voltage Protection (OVP) cameras, and notebooks with integrated Li-ion batteries Non-charging Accessory Detection that charge via USB connectors.
