FAN3988 USB / Charger and Over-Voltage Detection Device FAN3988 USB/Charger and Over-Voltage Detection Device Features Description The FAN3988 is a USB-connection-monitoring device Charger/USB Detection Device used to determine if a standard USB device or a battery- Charger/USB Device Detection Flag charging device is connected. Over-/Under-Voltage Detection Flag The FAN3988 sets the FLAG1 pin to logic HIGH or LOW as an indicator to the system controller that a V Supply: 2.7 V to 20 V BUS standard USB device or a charger is connected to the C of 1.5 pF ON USB port. The FAN3988 also monitors the V for BUS over- or under-voltage conditions. The FLAG2 pin is set 6-Lead MicroPak MLP Package LOW if V is less than 3.3 V or greater than 6.0 V. BUS Applications The FAN3988 is packaged in a very small 6-lead MicroPak MLP package suitable for small board Mobile Phones space applications, such as mobile phones.
