PI3USB9281 USB 2.0 Port Protection with Charger Detection Features Description USB-device charger detector PI3USB9281 provides external detection for any USB- Can tolerate USB3.0-PD 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 1.2 (BC1.2) DCP chargers per the CEA936 spec. It also integrates a power Battery Charging 1.2 (BC1.2) CDP switch with over-voltage and over-current protections. Battery Charging 1.2 (BC1.2) SDP The VBUSIN input pin can tolerate voltages up to 28V, Apple 1A, 2A, & 2.4A dedicated chargers which is important for USB3.0-PowerDelivery enabled Samsung-Fast chargers ports. The new USB-3.0-PowerDelivery specification YD/T-1951 dedicated chargers supports voltages up to 20V. CEA-936 Carkit 1 and 2 chargers The PI3USB9281 can operate over a temperature range Integrated Power FET of -40 to +85C. VBUS Tolerance up to 28V Typical applications involve portable & consumer 1.7A 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.
