CM1231

Two-Channel PicoGuard XP^TMESD Clamp Protection Array

Features

Product Description

•

Two channels of ESD protection

Exceeds ESD protection to IEC61000-4-2 Level 4:

12kV contact discharge (OUT pins)

The CM1231 is a member of the XtremeESD

product family and is specifically designed for next

generation deep submicron ASIC protection. These

devices are ideal for protecting systems with high data

and clock rates and for circuits requiring low capacitive

loading such as USB 2.0.

•

Two-stage matched clamp architecture

Matching-of-series resistor (R) of 10mΩ typical

Flow-through routing for high-speed signal integrity

Differential channel input capacitance matching of

0.02pF typical.

The CM1231 incorporates the PicoGuard XP

dual

•

Improved powered ASIC latchup protection

Dramatic improvement in ESD protection vs. best

in class single-stage diode arrays

stage ESD architecture which offers dramatically

higher system level ESD protection compared with

traditional single clamp designs. In addition, the

CM1231 provides a controlled filter roll-off for even

greater spurious EMI suppression and signal integrity.

The CM1231 protects against ESD pulses up to 12kV

contact on the “OUT” pins per the IEC 61000-4-2

standard.

•

40% reduction in peak clamping voltage

40% reduction in peak residual current

•

Withstands over 1000 ESD strikes*

Available in a SOT23-6 package

Applications

The device also features easily routed "pass-through"

differential pinouts in a 6-lead SOT23 package.

•

USB devices data port protection

General high-speed data line ESD protection

*Standard test condition is IEC61000-4-2 level 4 test circuit with each (A_OUT/B_OUT) pin subjected to 12kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one

continuous test run.
