USB Host Charger Identification
Analog Switches
General Description
Features
The MAX14566E/MAX14566AE/MAX14566BE are sec-
ond-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 (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 4.0I
(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.

to Q15kV Human Body Model (HBM). All the devices
are available in an 8-pin (2mm x 2mm) TDFN package,
and are specified over the -40NC to +85NC extended
temperature range.
Note: All devices are specified over the -40°C to +85°C oper-
ating temperature range.
