FAN3988 FAN3988 USB/Charger and Over-Voltage Detection Device Features Description Charger/USB Detection Device The FAN3988 FAN3988 is a USB-connection-monitoring device used to determine if a standard USB device or a batterycharging device is connected. Charger/USB Device Detection Flag Over-/Under-Voltage Detection Flag The FAN3988 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 FAN3988 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. VBUS Supply: 2.7V to 20V CON of 1.5pF 6 MLP Package Applications The FAN3988 FAN3988 is packaged in a very small 6-lead MLP package suitable for small board space applications, such as mobile phones.

FAN3988 FAN3988 - USB/Charger and Over-Voltage Detection Device Application Information Typical Application System with USB Transceiver With USB Transceiver (Figure 7) Without USB Transceiver (Figure 8) The FAN3988 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 FAN3988 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 FAN3988 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 FAN3988 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. In a standard USB configuration, there is a switch in the USB transceiver that is always ON in the full-speed mode. It is ON during the transition from full-speed mode to high-speed mode and is turned off after enumeration is complete. In a condition where a USB transceiver is not incorporated or there is a switch between the USB port and the FAN3988 FAN3988, external resistors must be used to set the correct input logic states on the FAN3988 FAN3988 D+ Dinputs. A 5M pull-down on the D- line and a 1M pullup to VDD on the D+ line are recommended. In a condition where D+ and D- are shorted when a charger is plugged into the USB port, the USB switch is ON and pulled to VDD, which is about 3V, making both D+ and D- HIGH and flag1 set HIGH ­ indicating that a charging device is connected to the port. When a condition exists where a charger is plugged into the USB port (D+ D- shorted), the voltage divider of 1M and 5M puts a voltage of 2.3V on the D+ D- inputs and flag1 is HIGH, indicating a charger is connected to port. In a condition where D+ and D- are connected to a standard USB device, the D+ is pulled to VDD and D- is set LOW (due to the 15K pull-down on the USB device) and flag1 is LOW. In a condition where the USB port is connected to a standard USB device, the D+ input is pulled up to VDD in parallel with the 1.5K on a USB transceiver with a parallel R value of 1.497K. The D- input is connected to a 15K pull-down by the USB device and in parallel with 5M with a parallel R value of 14.955K. This condition makes flag1 LOW. If D+ and D- are open (floating), D+ is pulled to VDD and D- floats LOW, which makes flag1 LOW. If D+ and D- are open (floating), D+ is pulled to VDD and D- floats LOW, which makes flag1 LOW. © 2007 Fairchild Semiconductor Corporation FAN3988 FAN3988 · Rev. 1.0.4 www.fairchildsemi.com 6 Control Battery Rsense Vbus Vbus DD+ Gnd Comparator OVP UVP Flag 2 Logic USB DD+ Std USB/ Charger Detect Logic Flag 1 GND 5M 1M Vdd Figure 8. © 2007 Fairchild Semiconductor Corporation Typical System Application without USB Transceiver www.fairchildsemi.com 2X 0.05 C 1.45 B 2X (1) 0.05 C (0.49) 5X 1.00 (0.75) (0.52) 1X A TOP VIEW 0.55MAX 55MAX (0.30) 6X PIN 1 0.05 C 0.05 0.00 RECOMMENED LAND PATTERN 0.05 C C 0.25 0.15 6X 1.0 DETAIL A 0.10 0.05 0.45 0.35 0.10 0.00 6X C B A C 0.40 0.30 FAN3988 FAN3988 - USB/Charger and Over-Voltage Detection Device Physical Dimensions 0.35 5X 0.25 0.40 5X 0.30 0.5 (0.05) 6X Notes: BOTTOM VIEW (0.13) 4X 0.075 X 45 CHAMFER DETAIL A PIN 1 TERMINAL 1.
