The MAX14566E/MAX14566AE/MAX14566BE are second-generation USB devices that combine Hi-Speed USB analog switches with a USB host charger (dedicated charger) identification circuit. These devices support both the latest USB Battery Charging Specification Revision 1.2 including data contact detection and a set resistor bias for Apple-compliant devices as well as legacy USB D+/D- short detection using data line pullup. The MAX14566E has a pMOSFET open-drain control output (active-low CEN) and the MAX14566AE has an nMOSFET open-drain control output (CEN) to restart the peripheral connected to the USB host.

These devices feature high-performance Hi-Speed USB switches with low 4pF (typ) on-capacitance and low 4.0Ω (typ) on-resistance. In addition, the devices feature a single digital input (CB) to switch between pass-through mode and autodetection charger mode. The USB host charger identification circuit allows a host USB port to support USB chargers with shorted DP/DM detection and to provide support for Apple-compliant devices using a resistor bias on USB data lines. When an Apple-compliant device is attached to the port in autodetection charger mode, the devices supply the voltage to the DP and DM lines from the internal resistor-divider. If a USB Revision 1.2-compliant device is attached, the devices short DP and DM to allow correct charger detection. The MAX14566BE features an additional digital input (CB1) to allow forced charger mode.

These devices have enhanced, high electrostatic discharge (ESD) protection on the DP and DM inputs up to ±15kV Human Body Model (HBM). All the devices are available in an 8-pin (2mm x 2mm) TDFN package and are specified over the -40°C to +85°C extended temperature range.
