• Level 3 MOS

• Apply for both Linear and Switching Application

• Accurate over the −55 to 125°C Temperature Range

• Model the Gate Charge, Transient, and Diode Reverse Recovery

Characteristics

DESCRIPTION

The attached spice model describes the typical electrical

characteristics of the p-channel vertical DMOS. The subcircuit

model is extracted and optimized over the −55 to 125°C

temperature ranges under the pulsed 0-V to 5-V gate drive. The

saturated output impedance is best fit at the gate bias near the

threshold voltage.

A novel gate-to-drain feedback capacitance network is used to model

the gate charge characteristics while avoiding convergence difficulties

of the switched C_gdmodel. All model parameter values are optimized

to provide a best fit to the measured electrical data and are not

intended as an exact physical interpretation of the device.

SUBCIRCUIT MODEL SCHEMATIC

This document is intended as a SPICE modeling guideline and does not constitute a commercial product data sheet. Designers should refer to the appropriate

data sheet of the same number for guaranteed specification limits.
