SPICE Device Model Si1405DL
P-Channel 1.8-V (G-S) MOSFET
CHARACTERISTICS
P-Channel Vertical DMOS Macro Model (Subcircuit Model) Level Apply both Linear Switching Application Accurate over 125°C Temperature Range Model Gate Charge, Transient, Diode Reverse Recovery Characteristics
DESCRIPTION
attached spice model describes typical electrical characteristics p-channel vertical DMOS. subcircuit model schematic extracted optimized over 125°C temperature ranges under pulsed gate drive. saturated output impedance best gate bias near threshold voltage. novel gate-to-drain feedback capacitance network used model gate charge characteristics while avoiding convergence difficulties switched model. model parameter values optimized provide best measured electrical data intended exact physical interpretation device.
