SAN JOSE, Calif. – March 4, 2010 –Fairchild Semiconductor (NYSE: FCS) offers designers of cell phones and handheld mobile products a device with highly integrated over-voltage protection (OVP) as well as USB/charger-detection capabilities. The newest member of Fairchild’s OVP family, the FAN3988, allows the end user the flexibility to select an external P-Channel MOSFET with the specific on-resistance and current capability required by the application.

The FAN3988 has built-in automatic detection allowing the device to sense the presence of a USB charger by continuously monitoring the D+ / D- lines for a shorted condition. In addition the device also monitors the VBUS for an over or under voltage condition. When an over-voltage threshold condition is reached the device will immediately disable the external P-Channel MOSFET. These features reduce the design complexity and eliminate external circuitry, saving board space. This new OVP device is ideal for addressing emerging standards for over voltage protection, which is particularly important for cell phones.

The FAN3988 is the newest member of a family of charger front-end integrated circuits designed to provide Li-ion batteries protection from failures of the charging circuit. Another member in the family is the FAN3989 which is similar to FAN3988 but includes a MOSFET inside the package. The FAN3988 is packaged in an ultra-compact 6-lead MicroPak™ MLP. It utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the IPC/JEDEC standard J-STD-020.
