Incorporating on-board FET, FAN3989 detects presence of USB charger, eliminating external circuitry, and resulting in 15-20% of board space savings. It also monitors VBUS for over or under-voltage conditions, setting FLAG 2 pin low if VBUS is under 3.3 V or over 6.0 V, while turning off internal PMOS load switch. Suited for cell phone applications, unit comes in compact 8-lead MLP packaging, utilizes Pb-free terminals, and meets IPC/JEDEC standard for Pb-free reflow requirements.
Fairchild Semiconductor's Over-Voltage Protection Device with USB/Charger-Detection Simplifies Design
o Saves 15 Percent Board Space for Portable Applications
SAN JOSE, Calif. - February 3, 2009 - Fairchild Semiconductor offers designers of cell phones, mobile audio, computer and consumer applications a highly integrated over-voltage protection (OVP) with USB/charger-detection. The FAN3989 incorporates an on-board FET and features built-in automatic detection allowing the device to sense the presence of a USB charger, all in a single package. This integrated automatic detection feature simplifies design by eliminating external circuitry, which in turn, saves 15 to 20 percent board space compared to discrete implementations. Its over-voltage protection capability is ideal for addressing emerging safety standards, which is particularly important for cell phones.
The FAN3989 acts as a USB connection monitoring device to determine if a USB device or a battery charging device is connected. The product will send a signal to the system controller to indicate the presence of a USB charging device. The FAN3989 also monitors VBUS for over or under-voltage conditions, setting the FLAG 2 pin low if VBUS is under 3.3V or over 6.0V, while turning off the internal PMOS load switch. These integrated features offer a more accurate approach when compared to typical discrete solutions.
"Recent issues regarding over-charging of portable devices have validated the need for increased protection," said Bill Boldt, senior marketing manager, Signal Conditioning products. "Standards bodies are issuing over-voltage protection recommendations to increase the safety of handheld products. The FAN3989 is instrumental in addressing these concerns and ensuring the safety of phones using chargers that are connected to a USB port."
The FAN3989 is packaged in ultra-compact 8-lead MLP packaging. It utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
