The MAX14550E is a USB Hi-Speed analog switch with a USB host charger (dedicated charger) identification circuit. The MAX14550E supports both the USB Battery Charging Specification Revision 1.0 and a set resistor bias for Apple®-compliant devices.

The MAX14550E features a high-performance Hi-Speed USB switch with low 4pF (typ) on-capacitance and low 4Ω (typ) on-resistance. In addition, the MAX14550E features two digital inputs (CB0 and CB1) to switch between pass-through and charger modes. The USB host charger identification circuit allows a host USB port to support USB chargers with shorted D+/D- detection and to provide support for Apple-compliant devices using a resistor bias. When an Apple-compliant device is attached to the port, the MAX14550E provides the voltage from the resistor-divider. The MAX14550E uses the internal or external resistor based on the voltage at RDP. If a USB Revision 1.0-compliant device is attached, the MAX14550E connects a short across DP and DM to allow correct charger detection. The MAX14550E autodetection circuit can be disabled and either a DP/DM short or resistor network is chosen as the default.

The MAX14550E has enhanced high electrostatic discharge (ESD) protection on the DP and DM inputs up to ±15kV Human Body Model (HBM).

The MAX14550E is available in a 10-pin (3mm x 3mm) TDFN package and is specified over the -40°C to +85°C extended temperature range.
