MAX14550E 19-4745 Rev 2 1/10 USB Host Charger Identification Analog Switch General Description Features The MAX14550E is a USB Hi-Speed analog switch with S USB 2.0 Hi-Speed Switching a USB host charger (dedicated charger) identification S Low 4.0pF On-Capacitance circuit. The MAX14550E supports both the USB Battery Charging Specification Revision 1.0 and a set resistor S Low 4.0 On-Resistance M bias for Apple -compliant devices. S Ultra-Low 0.1 On-Resistance Flatness The MAX14550E features a high-performance Hi-Speed S +2.8V to +5.5V Supply Range USB switch with low 4pF (typ) on-capacitance and low S Ultra-Low 7A Supply Current 4I (typ) on-resistance. In addition, the MAX14550E features two digital inputs (CB0 and CB1) to switch S Automatic USB Charger Identification Circuit between pass-through and charger modes. The USB S Optional External Resistor-Divider with Auto host charger identification circuit allows a host USB port Selection to support USB chargers with shorted D+/D- detection S 15kV High ESD HBM Protection on DP/DM and to provide support for Apple-compliant devices S 3mm x 3mm, 10-Pin TDFN Package using a resistor bias. When an Apple-compliant device is attached to the port, the MAX14550E provides the Applications voltage from the resistor-divider. The MAX14550E uses the internal or external resistor based on the voltage at Laptops RDP. If a USB Revision 1.0-compliant device is attached, Netbooks the MAX14550E connects a short across DP and DM to Cell Phones allow correct charger detection. The MAX14550E auto- detection circuit can be disabled and either a DP/DM Ordering Information short or resistor network is chosen as the default. The MAX14550E has enhanced high electrostatic dis- PIN- TOP PART TEMP RANGE charge (ESD) protection on the DP and DM inputs up to PACKAGE MARK Q15kV Human Body Model (HBM).

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = +2.8V to +5.5V, T = T = -40NC to +85NC, unless otherwise noted.
