FAN3989 — USB/Charger Detection Device with Load Switch November 2008 FAN3989 USB/Charger Detection Device with Load Switch Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ Charger/USB Detection Device with Load Switch Charger/USB Device Detection Flag Over/Under-Voltage Detection Flag Load Switch Output, Up to 1.5A Charge Current VBUS Supply: 2.7V to 20V CON of 1.5pF Package: 8 MLP 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.
