Description
The FAN3988 is a USB-connection-monitoring device
used to determine if a standard USB device or a battery-
charging device is connected.
The FAN3988 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 FAN3988 also monitors the V_BUS for
over- or under-voltage conditions. The FLAG2 pin is set
LOW if V_BUS is less than 3.3V or greater than 6.0V.
The FAN3988 is packaged in a very small 6-lead
MicroPak™ MLP package suitable for small board
space applications, such as mobile phones.
