PI3USB9281 – Micro USB Port Charger Detection with OVP and OCP Protection plus Full USB2.0 Data Switch The PI3USB9281 provides external detection for any USB-device and offers OVP (>6.8VA), OCP (>1.7A), and VBUS protection to withstand up to 28V. Device's ID connector interface can detect standard accessory or can be customized to detect specific accessories. It also detects various chargers available in the market, including car-chargers per the CEA936 spec. and non-charger accessories such as MHL and OTG. The PI3USB9281 also integrates a power switch with over-voltage and over-current protection. It is a USB2.0 data switch with 1.2GHz bandwidth and provides good eye diagram.
Latest chargers supported by the PI3USB9281: 12W Apple (5V, 2.4A), 10W Apple (5V, 2A), 5W Apple (5V, 1A) Samsung FAST charge Integrated Power FET USB BC1.2 – CDP, USB BC1.2 – SDP, USB BC1.2 – DCP Additional micro-B connector interface for non-charging sources such as USB OTG and MHL I2C programmability on all port registers by embedded controller Small Package: CSP 1.5 x 2.0 - 15L
