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 10-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 Cgd model. 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.
