Introduction
This application note describes the Input/Output Buffer
Information Specification (IBIS) model of the MC06XS4200,
MC10XS4200, and MC20XS4200 devices. These intelligent
high side switches are designed to be used in 24 V systems
such as trucks and busses. They can be used in some
industrial and 12 V applications as well. The low RDS(ON)
channels can control incandescent lamps, LEDs, solenoids,
or DC motors. Control, device configuration, and diagnostics
are performed through a 16-bit SPI interface, allowing easy
integration into existing applications. For a complete feature
description, please refer to the individual data sheets.

Model Description
IBIS file contain the basic signal models for each type of signal of device:
•
•
For input buffers: Input's capacitance and static pull-up/down currents
For output buffers: Output's capacitance, static/dynamic pull-up/down currents, propagation delay
For Dual 24 V High Side Switch, the IBIS model contains descriptions of
•
•
•
4 input buffers: CLOCK, SCLK, CSB, RSTB, SI, IN[0:1], CONF[0:1] pins
4 output buffers: FSB, SO, FSB, SYNC pins
Package parasitic elements
This model can be used to characterize I/V output curves, rise/fall transition waveforms, and device package
parasitic information. They cannot be used as a delay model for detailed timing analysis.
