Description

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.
