1 / 10 page November 2008 © 2007 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN3989 Rev. 1.0.3 FAN3989 USB/Charger Detection Device with Load Switch Features 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 Applications Mobile Phones Handheld Devices 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.
