N–Channel Enhancement–Mode Silicon Gate

The D2PAK package has the capability of housing a larger die
than any existing surface mount package which allows it to be used
in applications that require the use of surface mount components

capabilities. This advanced
high–cell density HDTMOS power FET is designed to withstand
high energy in the avalanche and commutation modes. This new
energy efficient design also offers a drain–to–source diode with a
fast recovery time. Designed for low voltage, high speed switching
applications in p ower supplies, converters and PWM m otor
controls, these devices are particularly well suited for bridge circuits
where diode speed and commutating safe operating areas are
critical and offer additional safety margin against unexpected
voltage transients.

Motorola TMOS Power MOSFET Transistor Device Data

POWER MOSFET SWITCHING

Switching behavior is most easily modeled and predicted
by recognizing that the power MOSFET is charge controlled.
The lengths of various switching intervals (∆t) are deter­mined by how fast the FET input capacitance can be charged
by current from the generator.

The published capacitance data is difficult to use for calculat­ing rise and fall because drain–gate capacitance varies
greatly with applied voltage. Accordingly , gate charge data is
used. In most cases, a satisfactory estimate of average input
current (I

G(AV)

) can be made from a rudimentary analysis of

the drive circuit so that
t = Q/I

G(AV)

During the rise and fall time interval when switching a resis­tive load, VGS remains virtually constant at a level known as
the plateau voltage, V

SGP

. Therefore, rise and fall times may

be approximated by the following:
tr = Q2 x RG/(VGG – V

GSP

)

tf = Q2 x RG/V

GSP

where
VGG = the gate drive voltage, which varies from zero to V

GG

RG = the gate drive resistance
and Q2 and V

GSP

are read from the gate charge curve.

During the turn–on and turn–off delay times, gate current is
not constant. The simplest calculation uses appropriate val­ues from the capacitance curves in a standard equation for
voltage change in an RC network. The equations are:

t

d(on)

= RG C

iss

In [VGG/(VGG – V

GSP

)]

t

d(off)

= RG C

iss

In (VGG/V

GSP

)

The capacitance (C

iss

) is read from the capacitance curve at
a voltage corresponding to the off–state condition when cal­culating t

d(on)

and is read at a voltage corresponding to the

on–state when calculating t

d(off)

.

At high switching speeds, parasitic circuit elements com­plicate the analysis. The inductance of the MOSFET source
lead, inside the package and in the circuit wiring which is
common to both the drain and gate current paths, produces a
voltage at the source which reduces the gate drive current.
The voltage is determined by Ldi/dt, but since di/dt is a func­tion of drain current, the mathematical solution is complex.
The M OSFET output capacitance also complicates the
mathematics. And finally, MOSFETs have finite internal gate
resistance which effectively adds to the resistance of the
driving source, but the internal resistance is difficult to mea­sure and, consequently, is not specified.

The resistive switching time variation versus gate resis­tance (Figure 9) shows how typical switching performance is
affected by the parasitic circuit elements. If the parasitics
were not present, the slope of the curves would maintain a
value of unity regardless of the switching speed. The circuit
used to obtain the data is constructed to minimize common
inductance in the drain and gate circuit loops and is believed
readily achievable with board mounted components. Most
power electronic loads are inductive; the data in the figure is
taken with a resistive load, which approximates an optimally
snubbed inductive load. Power MOSFETs may be safely op­erated into an inductive load; however, snubbing reduces
switching losses.
