FAN3989

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 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 internal load switch control pin is set HIGH if V_BUS is less than 3.3V or greater than 6.0V, turning off the PMOS switch.The FAN3989 is available in a very small 8-lead MLP package suitable for small board space applications, like mobile phones.
