PRODUCT DESCRIPTION

format product datasheet

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.

The CM1231 incorporates the PicoGuard XP® dual 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.

The device also features easily routed "pass-through" differential pinouts in a 6-lead SOT23 package.


FEATURES

APPLICATIONS

  • Two channels of ESD protection
  • Exceeds ESD protection to IEC61000-4-2 Level 4, ±12kV contact discharge (OUT pins)
  • 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.
  • Improved powered ASIC latchup protection
  • Dramatic improvement in ESD protection vs. best in class single-stage diode arrays
    • 40% reduction in peak clamping voltage
    • 40% reduction in peak residual current
  • Withstands over 1000 ESD strikes*
  • Available in a SOT23-6 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 (AOUT/BOUT) 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.
