8 Line ESD/EMI Protection for Color LCD Interfaces
UM8401 DFN16 4.0×1.6
General Description
The UM8401 is a low pass filter array with integrated TVS diodes. It is designed to suppress
unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic
equipment. This state-of-the-art device utilizes silicon-avalanche technology for superior clamping
performance and DC electrical characteristics. It has been optimized for protection of color LCD
panels in cellular phones and other portable electronics.
The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and a RC
network for EMI filtering. A series resistor value of 100Ω and a capacitance value of 10pF are used to
achieve 25dB minimum attenuation from 800 MHz to 2.5GHz. The TVS diodes provide effective
suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per
IEC 61000-4-2, level 4.
The UM8401 is in a 16-pin, RoHS compliant DFN16 package. It measures 4.0mm×1.6mm. The leads
are spaced at a pitch of 0.5mm and are finished with lead-free Ni Pd. The small package makes it
ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.
