The following precautions should be followed when testing
TOPSwitch-GX
by itself outside of a power supply. The
schematicshowninFigure53issuggestedforlaboratorytesting
of TOPSwitch-GX.
When the DRAIN pin supply is turned on, the part will be
in the auto-restart mode. The CONTROL pin voltage will be
oscillating at a low frequency between 4.8 V and 5.8 V and
the drain is turned on every eigth cycle of the CONTROL pin
oscillation. If the CONTROL pin power supply is turned on
while in this auto-restart mode, there is only a 12.5% chance
that the CONTROL pin oscillation will be in the correct state
(drainactivestate)sothatthecontinuousdrainvoltagewaveform
may be observed. It is recommended that the V
C power supply
be turned on rst and the DRAIN pin power supply second if
continuous drain voltage waveforms are to be observed. The
12.5% chance of being in the correct state is due to the divide-
by-8 counter. Temporarily shorting the CONTROL pin to the
SOURCE pin will reset TOPSwitch-GX, which then will come
up in the correct state.
