DESCRIPTION
The TD310 is designed to drive one, two or three
Power IGBT/MOS and has driving capability for
pulse transformer. So it is perfectly suited to inter-
face control IC with Power Switches in low side or
half-bridge configuration.
The typical application shown figure 1 implements
the TD310 in a pulse controlled half-bridge drive.
Positive and negative pulses are applied to the
pulse transformer to charge and discharge the
IGBT/MOS gate capacitance. More sophisticated
secondary circuits provide low impedance gate
drive and short-circuit protectionas shownin appli-
cation note n°AN461.

On Figure 2, TD310 is implemented as a low side
driver in a typical 3 phase motor drive.
Figure 3 presents a general purpose low side gate
drive.
