Description
Esd/emi Protection For Color Lcd Interfaces
Manufacturer
Semtech Corporation
Datasheet
The EClamp
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 solid-
state silicon-avalanche technology for superior clamp-
ing performance and DC electrical characteristics.
They have been optimized for protection of color
LCD panels
LCD panels
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 resistor -
capacitor network for EMI/RFI filtering. A series
resistor value of 200 and a capacitance value of 12pF
are used to achieve 30dB minimum attenuation from
800MHz to 2.7GHz. 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 EClamp2388P is in a 16-pin, RoHS/WEEE compli-
ant, SLP4016P16 package. It measures 4.0 x 1.6 x
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPd. The small pack-
age makes it ideal for use in portable electronics such
as cell phones, digital still cameras, and PDAs.
