The FAN3989 is a USB-connection-monitoring device
used to determine if a standard USB device is
connected or a battery changing device is connected.
The FAN3989 sets the FLAG1 pin to logic HIGH or
LOW as an indicator to the system controller that a
standard USB device or a charger is connected to the
USB port. The FAN3989 also monitors the VBUS for
over- or under-voltage conditions. The FLAG2 pin is set
LOW if VBUS is less than 3.3V or greater than 6.0V. The
internal LS CTRL (load switch control) pin is set HIGH if
VBUS is less than 3.3V or greater than 6.0V, turning off
the PMOS switch.
The FAN3989 is packaged in a very small 8-lead MLP
package suitable for small board space applications,
like mobile phones.
